Sažetak (engleski)
We report measurements of the charge-separated W+(-)→e+(- )+νe(ν̅ e) and Z/γ*→e+e- 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-ν̅ 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)-0.9+0.5(syst)±1.0(lumi)  pb was measured for di- lepton invariant masses me+e- between 70 and 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. Theoretical predictions, calculated using recent parton distribution functions, are found to agree with the measured cross sections.
