Non-strange vector meson production in K$^{-}$p interactions at 4.2 GeV/c

The vector meson production, hypercharge exchange reactions K/sup -/p to ( phi , omega , rho ) Lambda and ( phi , rho ) Sigma /sup 0/ are studied at 4.2 GeV/c incident momentum. The data come from a high statistics bubble chamber experiment with a sensitivity of approximately 120 events/ mu b. Total...

Descripción
Sumario:The vector meson production, hypercharge exchange reactions K/sup -/p to ( phi , omega , rho ) Lambda and ( phi , rho ) Sigma /sup 0/ are studied at 4.2 GeV/c incident momentum. The data come from a high statistics bubble chamber experiment with a sensitivity of approximately 120 events/ mu b. Total and differential cross sections are presented. The vector meson density matrix elements and hyperon polarization are investigated as functions of momentum transfer. Amplitude analyses are performed for all five reactions. The results are compared with duality and quark model predictions, as well as used to test current ideas in two-body phenomenology. (35 refs).
