Measurements of $W$ and $Z/{\gamma }^{\ast }$ cross sections and their ratios in $p+p$ collisions at RHIC

STAR Collaboration, J. Adam, L. Adamczyk +356

We report on the $W$ and $Z/{\gamma }^{\ast }$ differential and total cross sections as well as the $W^{+}$/$W^{-}$ and $(W^{+}+W^{-})$/$(Z/{\gamma }^{\ast })$ cross-section ratios measured by the STAR experiment a…
