Using the SLAC 1-m bubble chamber to study a sample of 178×103 interactions, we find a signal of centrally produced direct e+e- pairs which accounts for (4813)% of all e+e- pairs detected with |x|<0.02 and PT<10 MeV/c. This measurement agrees with a calculation of e+e- pair production from the internal conversion of hadronic bremsstrahlung. © 1981 The American Physical Society.}, Doi = {10.1103/PhysRevD.24.2829}, Key = {fds341228} } @article{fds341230, Author = {GOSHAW, AT and ELLIOTT, JR and EVANS, LE and FORTNEY, LR and LUCAS, P and ROBERTSON, W and WALKER, WD and SUN, CR and KIM, IS}, Title = {DIRECT GAMMA-PRODUCTION FROM PI+-P COLLISIONS AT 10.5 AND 15.0 GEV-C.}, Journal = {BULLETIN OF THE AMERICAN PHYSICAL SOCIETY}, Volume = {24}, Number = {4}, Pages = {601-601}, Publisher = {AMER INST PHYSICS}, Year = {1979}, Month = {January}, Key = {fds341230} } @article{fds341229, Author = {Goshaw, AT and Lucas, PW and Walker, WD and Elliott, JR and Evans, LE and Fortney, LR and Robertson, WJ and Kim, IJ and Sun, CR}, Title = {Direct photon production from +p interactions at 10.5 GeV/c}, Journal = {Physical Review Letters}, Volume = {43}, Number = {15}, Pages = {1065-1068}, Year = {1979}, Month = {January}, url = {http://dx.doi.org/10.1103/PhysRevLett.43.1065}, Abstract = {We have studied inclusive photon production from +p interactions at 10.5 GeV/c and found a source of centrally produced direct photons which accounts for (469)% of all photons detected with PL* and PT between 0 and 20 MeV/c.

If the anomalous branching ratio of 2πK̄K of the isosinglet member of the octet is accounted for by SU3 violation, the resulting octet-dominance-violating contribution to the mass formula very much improves the Gell-Mann-Okubo mass relations for pseudoscalar mesons. © 1968 The American Physical Society.}, Doi = {10.1103/PhysRev.168.1706}, Key = {fds341232} } @article{fds343713, Author = {Cook, CL and Evans, LE and Han, MY and Lipshutz, NR and Straumann, N}, Title = {Sum rules and the electromagnetic mass difference of pions}, Journal = {Nuclear Physics, Section B}, Volume = {5}, Number = {1}, Pages = {140-146}, Year = {1968}, Month = {April}, url = {http://dx.doi.org/10.1016/0550-3213(68)90216-2}, Abstract = {Using the algebra of currents, we show that the electromagnetic pion mass-difference diverges in the soft-pion limit, if the usual spectral sum rules are assumed.
