Measurement of the W$^+$W$^-$ cross section in pp collisions at 8 TeV and limits on anomalous gauge

A measurement of the W+W- production cross section in pp collisions at 8TeV is presented. The data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 19.4 /fb.. The W+W- candidates are selected in events with two charged leptons, electrons or muons, and la...

description A measurement of the W+W- production cross section in pp collisions at 8TeV is presented. The data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 19.4 /fb.. The W+W- candidates are selected in events with two charged leptons, electrons or muons, and large missing transverse energy. The W+W- cross section is measured to be 60.1+-0.9 (stat.) +- 3.2 (exp.) +- 3.1 (th.) +- 1.6 (lum.) pb.

The data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 19.4 /fb.. The W+W- candidates are selected in events with two charged leptons, electrons or muons, and large missing transverse energy. The W+W- cross section is measured to be 60.1+-0.9 (stat.) +- 3.2 (exp.) +- 3.1 (th.) +- 1.6 (lum.) pb.A measurement of the W boson pair production cross section in proton-proton collisions at √ s = 8 TeV is presented. The data 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 σ ( pp → W + W − ) = 60.1 ± 0.9 (stat.) ± 3.2 (exp.) ± 3.1(th.) ± 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. The corresponding 95% confidence level intervals are -5.7 < c www / Λ 2 < 5.9 TeV − 2 , -11.4 < c w / Λ 2 < 5.4 TeV − 2 , 29.2 < c B / Λ 2 < 23.9 TeV − 2 , in the HISZ basis.SISSACMS-CR-2015-246oai:cds.cern.ch:2065116oai:inspirehep.net:15007812015-10-15
