B Production In p-p and A-A Collisions

Abstract

This is an extension of our recent work on $D^{+}(c\bar{d}),D^o(c\bar{u})$ production from p-p and d-Au collisions to $B^{+}(b\bar{d}),B^o(b\bar{u})$ production from p-p and A-A collisions. The rapidity cross sections for $B^{+}(c\bar{d}),B^o(b\bar{u})$ production from both p-p and A-A collisions are estimated. Our present work makes use of previous work on $J/\Psi$, ${\Psi }^{\prime }(2S)$, ${\rm Y}(nS)$ production in p-p and A-A collisions, with the main new aspect being the fragmentation probability, $D_{b\to b\bar{q}}$, which turns out to be similar to the fragmentation probability $D_{c\to c\bar{q}}$ used in our recent work.
