D Production In p-p and d-Au Collisions

Abstract

This is an extension of our previous work on $J/\Psi$, $\Psi'(2S)$, $\Upsilon(nS)$ production in p-p and A-A collisions to the production of $D^+(c\bar{d}),D^o(c\bar{u})$, with the main new aspect being the fragmentation probability, $D_{c \rightarrow c\bar{q}}$, which has been calculated almost two decades ago. The rapidity cross sections for $D^+(c\bar{d}),D^o(c\bar{u})$ production from both p-p and d-AU collisions is estimated.
