Measurements of the Differential Cross Section and Charge Asymmetry for Inclusive Pp→W(mn) Production with 8 TeV CMS Data and CMS Single Muon Trigger Efficiency Study

Measurement of the Differential Cross Section and Charge Asymmetry for Inclusive $$\mathrm {p}\mathrm {p}\rightarrow \mathrm {W}^{\pm }+X$$ Production at $${\sqrt{s}}

The differential cross section and charge asymmetry for inclusive pp → W± + X → [mu]±[nu] + X production at √s = 8 TeV are measured as a function of muon pseudorapidity. The data sample corresponds to an integrated luminosity of 18.8 inverse femtobarns recorded with the CMS detector at the LHC. Furthermore, these results provide important constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10E-3 to 10E-1.

Measurement of the $W^+W^-$ Cross Section in Pp Collisions at $\sqrt{s}$

A measurement of the W boson pair production cross section in proton-proton collisions at [arrow]"s = 8 TeV is presented. The data we collected with the CMS detector at the LHC correspond to an integrated luminosity of 19.4 fb-1 . The W+W- candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The measured W+W- cross section is 60.1 " 0.9 (stat) " 3.2 (exp) " 3.1 (theo) " 1.6 (lumi) pb = 60.1 " 4.8 pb, consistent with the standard model prediction. The W+W-cross sections are also measured in two different fiducial phase space regions. The normalized differential cross section is measured as a function of kinematic variables of the final-state charged leptons and compared with several perturbative QCD predictions. Limits on anomalous gauge couplings associated with dimension-six operators are also given in the framework of an effective field theory. Finally, the corresponding 95% confidence level intervals are -5.7
