Inclusive Vector Meson Production in Fragmentation Regions of Meson at Small PT

Inclusive vector meson spectra in fragmentation regions of meson at small PT are studied from a two·component model (quark fragmentation and triple Regge contributions). It is shown that our model can explain successfully various inclusive vector meson spectra. The analyses of this paper show that quark decay functions into vector mesons are nearly the same as those into pseudo-scalar mesons and the strange quark suppression factor :::-=0.2, which is nearly the same as in pseudo-scalar meson production.
