Abstract = {Weak interactions are expected to induce a parity violating
pion-nucleon coupling, hπNN(1). This coupling should be
measurable in a proposed experiment to study the parity
violating asymmetry Aγ in the process n→ + p → d + γ.
We compute the leading dependence of Aγ on the coupling
hπNN(1) using recently developed effective field theory
techniques and find an asymmetry of Aγ = + 0.17 hπNN(1) at
leading order. This asymmetry has the opposite sign to that
given by Desplanques and Missimer. © 1999 Published by

Abstract = {We analyze parity-violating nucleon-nucleon scattering at
energies E < mπ2 / M using the effective field theory
appropriate for this regime. The minimal Lagrangian for
short-range parity-violating NN interactions is written in
an operator basis that encodes the five partial-wave
transitions that dominate at these energies. We calculate
the leading-order relationships between parity-violating NN
asymmetries and the coefficients in the Lagrangian and also
discuss the size of sub-leading corrections. We conclude
with a discussion of further observables needed to
completely determine the leading-order Lagrangian. © 2009

Abstract = {This paper explores whether Eguchi-Kawai reduction for gauge
theories with adjoint fermions is valid. The Eguchi-Kawai
reduction relates gauge theories in different numbers of
dimensions in the large N limit provided that certain
conditions are met. In principle, this relation opens up the
possibility of learning about the dynamics of 4D gauge
theories through techniques only available in lower
dimensions. Dimensional reduction can be understood as a
special case of large N equivalence between theories related
by an orbifold projection. In this work, we focus on the
simplest case of dimensional reduction, relating a 4D gauge
theory to a 3D gauge theory via an orbifold projection. A
necessary condition for the large N equivalence between the
4D and 3D theories to hold is that certain discrete
symmetries in the two theories must not be broken
spontaneously. In pure 4D Yang-Mills theory, these
symmetries break spontaneously as the size of one of the
spacetime dimensions shrinks. An analysis of the effect of
adjoint fermions on the relevant symmetries of the 4D theory
shows that the fermions help stabilize the symmetries. We
consider the same problem from the point of view of the
lower dimensional 3D theory and find that, surprisingly,
adjoint fermions are not generally enough to stabilize the
necessary symmetries of the 3D theory. In fact, a rich phase
diagram arises, with a complicated pattern of symmetry
breaking. We discuss the possible causes and consequences of
this finding. © 2009 SISSA.},

Abstract = {We calculate the cold neutron-deuteron (nd) capture cross
section,σnd to next-to-next-to leading order (NNLO) using
the model-independent approach of pionless effective-field
theory [EFT(π)]. At leading order we find σnd=0.314±0.217
mb, while the experimental result is 0.508(15) mb [Phys.
Rev. C 25, 2810 (1982)10.1103/PhysRevC.25.2810] for a
laboratory neutron velocity of 2200 m/s. At
next-to-leading-order (NLO), we show that σnd is sensitive
to the low-energy constant (LEC) L1(0) of the two-nucleon
isovector current appearing at NLO. A fit of L1(0) at NLO to
the triton magnetic moment yields a NLO prediction of
σnd=0.393±0.164 mb, where the error comes from propagating
the error from the L1(0) fit. At NNLO, we find that a new
three-nucleon magnetic moment counterterm is required for
renormalization-group invariance of both σnd and the triton
magnetic moment. Fitting the NNLO correction to L1(0)
(denoted L1(1)) to cold neutron-proton capture (σnp) yields
a NNLO prediction of σnd=0.447±0.130 mb, where the error
comes from propagating the error from the L1(1) fit. We also
study different fittings of L1(0) and L1(1) to σnp, σnd,
and/or the triton magnetic moment. For example, fitting
L1(0) simultaneously to σnp, σnd, and the triton magnetic
moment at NLO, and fitting L1(1) simultaneously to σnp and
σnd at NNLO, yields σnd=0.480±0.114 mb and 0.511±0.042
mb, respectively, where errors are naively estimated from
EFT(π) power counting. In addition, we discuss how Wigner
SU(4) symmetry may alter the naive EFT(π) expansion of
σnd.},

Abstract = {We compute the leading contributions to the magnetic dipole
and electric quadrupole moments of the baryon decuplet in
chiral perturbation theory. The measured value for the
magnetic moment of the Ω- is used to determine the local
counterterm for the magnetic moments. We compare the chiral
perturbation theory predictions for the magnetic moments of
the decuplet with those of the baryon octet and find
reasonable agreement with the predictions of the large-Nc
limit of QCD. The leading contribution to the quadrupole
moment of the Δ and other members of the decuplet comes
from one-loop graphs. The pionic contribution is shown to be
proportional to Iz (and so will not contribute to the
quadrupole moment of I=0 nuclei), while the contribution
from kaons has both isovector and isoscalar components. The
chiral logarithmic enhancement of both pion and kaon loops
has a coefficient that vanishes in the SU(6) limit. The
third allowed moment, the magnetic octupole, is shown to be
dominated by a local counterterm with corrections arising at
two loops. We briefly mention the strange counterparts of
these moments. © 1994 The American Physical

Abstract = {We investigate the weak kaon-nucleon (NNK) S-wave and P-wave
interactions using heavy baryon chiral perturbation theory.
The leading one-loop SU(3) breaking contributions to the
ppK, pnK, and nnK couplings are computed. We find that they
suppress all NNK amplitudes by 30% to 50%. The ratio of
neutron-induced to proton-induced hypernuclear decay widths
is sensitive to such reductions. It has been argued that the
discrepancy between the predicted and observed P-wave
amplitudes in Δs = 1 hyperon decay results from an
accidental cancellation between tree-level amplitudes, and
is not a fundamental problem for chiral perturbation theory.
Agreement between experimentally determined NNK P-wave
amplitudes and our estimates would support this
explanation.},

recently showed that, for the light Majorana exchange
formalism, effective field theory calculations require a
nn→ppe-e- contact term at leading order. They estimated
the size of this contribution by relating it to measured
charge-independence-breaking (CIB) nucleon-nucleon
interactions and making an assumption about the relative
sizes of CIB operators. We show that the assumptions
underlying this approximation are justified in the limit of
the number of colors, Nc, being large. We also obtain a
large-Nc hierarchy among CIB nucleon-nucleon interactions

scattering, these operators contribute to S-P and P-D wave
transitions, with five operators and their accompanying low

transitions and six operators and LECs those in P-D
transitions. We show that the large-Nc analysis separates
them into leading order in Nc, next-to-leading order in Nc,
etc. Relationships among EFTπ/ LECs emerge in the large-Nc
expansion. We also discuss the renormalization group (RG)
scale dependence of these LECs by considering two distinct
limits: one in which large-Nc relationships among LECs hold
but RG-related approximate expansions do not, and vice
versa. Our analysis can complement lattice QCD calculations

Abstract = {The symmetries of the standard model dictate that for very
low energies, where nucleon dynamics can be described in
terms of a pionless effective field theory (EFT(π/)), the
leading-order parity-violating nucleon-nucleon Lagrangian
contains five independent unknown low-energy constants
(LECs). We find that imposing the approximate symmetry of
QCD that appears when the number of colors Nc becomes large
reduces the number of independent LECs to two at leading
order in the combined EFT(π/) and large-Nc expansions. We
also find a relation between the two isoscalar LECs in the
large-Nc limit. This has important implications for the
number of experiments and/or lattice calculations necessary
to confirm this description of physics. In particular, we
find that a future measurement of the parity-violating
asymmetry in γ - d→np together with the existing result
for parity-violating p - p scattering would constrain all
leading-order (in the combined expansion) LECs. This is a
considerable improvement on the previous understanding of
the system.},

effects of heavy quarks s, c and b. At the hadronic scale,
the hamiltonian contains four-quark operators of the u, d,

QCD corrections from running between the weak scale and the
hadronic scale. The coefficients of the operators involving
the s quark are substantially larger than those of the
operators involving only the u and d quarks. Recent EMC
measurements of the spin-dependent proton structure
functions g1p (x) and measurements of the low-Q2 axial
nucleon-Z0 coupling from neutrino scattering indicate that
the nucleon matrix element of the strange vector axial
current is substantial. Assumming that the weak amplitude
factorizes, this matrix element gives rise to an enhancement
in the weak isovector parity violating NNρ{variant}

hadron dynamics, we discuss the radiative decay of the
baryon decuplet to the baryon octet and compute the leading
non-analytic SU(3) violating corrections induced at the
one-loop level. In the limit of exact flavour SU(3) symmetry
two of the possible decay modes are forbidden and the rates
for these two decays are dominated by loop corrections.
There is only one SU(3) conserving contact term at leading
order in chiral perturbation theory for the radiative
decays. We determine its coefficient from the observed
branching ratio for Δ → Nγ and from the present upper
limit on Ξ*0 → Ξ0γ. We then predict the branching
fractions for Σ*- → Σ- γ, Σ*0 → Λγ, Σ*0 →
Σ0γ, Σ*+ → Σ+ γ, Ξ*0γ → Ξ0γ and Ξ*- → Ξ-γ.
Some of the decay modes are predicted to have branching
fractions near the current experimental upper limit and
could possibly be observed in the near future. The leading
corrections to the octet-decuplet-meson strong coupling
constant, C, are computed at one-loop and the strong decay
rates of the Δ, Σ*and Ξ* allow us to determine |C| = 1.2
± 0.1 and H = -2.2 ± 0.6, in remarkable agreement with
predictions based on spin-flavour symmetry. We calculate the
Δ pole graph contribution to the polarisability of the

containing two b quarks (or one b and one c quark—many
relationships are the same) in terms of unknown reduced
matrix elements. This project was originally motivated by
the request of the Fermilab run II b Physics Workshop
organizers for a guide to experimentalists in their search
for as yet unobserved hadrons. We include an analysis of
linear SU(3) breaking terms in addition to relationships
generated by unbroken SU(3) symmetry, and relate these to
expressions in terms of the complete set of possible reduced
matrix elements. © 2003 The American Physical

of the deuteron using effective field theory. The momentum
dependence of the anapole form factor is different from that
of the matrix element of the strange currents in the
deuteron, which may provide a way for disentangling these
two competing effects when analyzing parity-violating
electron-deuteron scattering experiments. We give closed

calculated using the recently developed effective field

contributions starting at next-to-leading order from the
exchange of a single potential pion and is found to be αE2

introducing the different methods that have been used to
study parity-violating observables we discuss the available

Particular emphasis is put on effective field theory
calculations where they exist, but earlier and complementary
approaches are also presented. We hope this review will
serve as a guide for those who wish to know what
calculations are available and what further calculations
need to be completed before we can claim to have a
comprehensive picture of parity violation in few nucleon

Abstract = {The X(3872) has non-charmonium-like properties, such as
decay processes that seem to violate isospin, and a mass
that lies unexpectedly close to the D0 D̄0* threshold. An
effective field theory that includes both charmoniumlike
(short-distance) and moleculelike (meson bound state)
properties is used to analyze the X(3872) as it is produced
in the decay of ψ(4160). This is a route that BESIII may be
able to measure. We find that the correlation between the
angular distribution of the outcoming photon [or X(3872)]
and the polarization of the ψ(4160) source may be used to
provide information on whether short-distance or
long-distance effects dominate. © 2013 American Physical
