60. EWK di-boson production in ATLAS (15'+5')

Johannes Ebke (Ludwig-Maximilians-Univ. Muenchen)

The production of pairs of bosons is an important process for investigating the electroweak sector of the Standard Model. We present measurements of the diphoton, Z+photon, W+photon and WW production cross sections. Constraints on the couplings are also presented.

63. Status of Higgs and EW cross-sections for the LHC (20'+5')

Fulvio Piccinini (INFN Pavia)

A short review of the status of theoretical calculations and their uncertainties for the most relevant electroweak processes at the LHC is presented

64. Vector boson production in ATLAS (15'+5')

Lashkar Kashif (University of Wisconsin-Madison)

Electroweak bosons are a "standard candle" process for physics at the LHC. We present measurements of total inclusive W and Z production cross sections, as well as differential cross sections and the W charge asymmetry.

65. Study of W and Z production, lepton charge asymmetry and Z differential cross sections at CMS (15'+5')

Hwidong Yoo (Purdue University)

We present various measurements with W and Z bosons, based on 36 inverse-picobarns of pp collisions at √s = 7 TeV recorded by the CMS detector at the LHC in 2010. The results, obtained in the electron and muon channels, are compared to predictions at the NLO or NNLO in QCD using recent sets of parton densities. We first report on the inclusive W- and Z-boson production cross sections, measured...

66. Studies of electroweak boson production in the forward region with LHCb (15'+5')

Stephen Farry (UC Dublin)

We report on measurements of W+, W– and Z0 production, using data taken by the LHCb experiment at sqrt(s) = 7 TeV during 2010. The electroweak bosons are reconstructed by selecting decays to muonic final states. The cross-sections are measured within the region 2 < eta < 4.5, using muons of transverse momenta exceeding 20 GeV/c, as well as differentially as a function of lepton pseudorapidity...
