Ra. Williams et al., KINEMATICALLY ACCESSIBLE VECTOR-MESON RESONANCE ENHANCEMENTS IN P(K-,E-)LAMBDA,SIGMA-0,LAMBDA(1405)(E), Physical review. C. Nuclear physics, 48(3), 1993, pp. 1318-1322
Calculations for the kaon capture, electron pair, and hyperon (Y) prod
uction reactions, p(K-,e+e-)Y, are made for Y = LAMBDA, SIGMA0, and LA
MBDA(1405) using our previously developed crossing and duality constra
ined electroproduction model. Because there is no constraint on the mi
nimum 4-momentum transferred by the timelike photon (q2 greater-than-o
r-equal-to 2M(e)2 is similar to 0), we observe that the low-lying rho,
omega and phi vector mesons are kinematically accessible, producing u
p to four orders of magnitude enhancement in the theoretical hyperon p
roduction cross section. We also discuss the significance and utility
of this dramatic enhancement for investigating several important topic
s of current interest.
