Abstract

We propose a method to extract the charm structure function of the nucleon $c (x, Q^{2} = m_{W}^{2})$ from measurements of the rapidity distribution of $W^{\pm}$ and $Z$ in $p \bar{p}$ collisions. The production of weak intermediate bosons via charm occurs at the few percent level at the Fermilab Tevatron and has in particular a strong influence on the important measurements of the ratio of $W$ and $Z$ events as $c \bar{s} \to W$ is expected to be much larger than $c \bar{c} \to Z$ .
