Description
| - We report measurements of the charge-separated W +(-) -> e+(-) + νe(ν e) and Z/γ* -> e+e- root production cross sections at mid-rapidity in proton-proton collisions at s = 500 GeV. These results are based on 13.2 pb-1 of data recorded in 2009 by the STAR detector at RHIC. Production cross sections for W bosons that decay via the eν channel were measured to be σ(pp -> W+X).BR(W+ -> e+ νe) = 117.3 ± 5.9(stat) ± 6.2(syst) ± 15.2(lumi) pb, and σ(pp -> W-X).BR(W- -> e- ν e) = 43.3 ± 4.6(stat) ± 3.4(syst) ± 5.6(lumi) pb. For Z/γ* production, σ(pp -> Z/γ* X) . BR(Z/γ* -> e+e-) = 7.7 ± 2.1(stat) +0.5(syst) ± 1.0(lumi) pb for di-lepton invariant masses m + - between 70 and -0.9 ee root 110 GeV/c2. First measurements of the W cross section ratio, σ(pp -> W+X)/σ(pp -> W-X), at s = 500 GeV are also reported.
