Abstract:
We make predictions for the kaon
interferometry measurements
in Au+Au collisions at the Relativistic Heavy
Ion Collider
(RHIC). A first order phase transition from a
thermalized
Quark-Gluon-Plasma (QGP) to a gas of hadrons
is assumed for
the transport calculations. The fraction of
kaons that are
directly emitted from the phase boundary is
considerably
enhanced at large transverse momenta K_T ~ 1
GeV/c. In this
kinematic region, the sensitivity of the
R_out/R_side ratio
to the QGP-properties is enlarged. Here, the
results of the
1-dimensional correlation analysis are
presented. The
extracted interferometry radii, depending on
$K_T$, are not
unusually large and are strongly affected by
momentum
resolution effects.
