Query: D Production In p-p and d-Au Collisions   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.
