  We estimate the production of $Z^a$ bosons via p-p collisions using previous
work on $J/\Psi$, $\Psi(2S)$ production in p-p collisions, with the new aspect
being the creation of $Z^a$ bosons via quark interactions, with $a$ the
component of a $Z$ vector boson. We then estimate the production of $Z^a$
bosons via Pb-Pb collisions using modification factors from previous
publications.
