“…The 2010 data is used to measure the cross sections of the $Z$, $W^{+}$ and $W^{-}$ bosons which are then used with the HERA deep inelastic scattering data to determine the strange quark density of the proton. Three analyses that use 2011 data are shown; a measurement of the forward-backward asymmetry of the $Z/\gamma^{*}$ boson, from which the effective weak mixing angle is extracted; a measurement of the angular correlations of Drell-Yan lepton pairs from resonant $Z$ decays; and a measurement of the high mass Drell-Yan differential cross section.…”

“…The latter model is studied in assumptions of either gluon--gluon or quark--antiquark production mechanisms. The limit on the fractional presence of a pseudoscalar component is $\sigma(0-) / [\sigma(0+) + \sigma(0-)] < 0.58\%$ at 95\% CL.…”
