Standard Model & Beyond
At the LHC, the processes with several particles in the final states occur routinely. These processes provide a new domain to test the standard model. Some of these processes can be discovery/confirmation channel for beyond the standard model scenarios also. Therefore, it is important to compute the contribution of the standard model to such multiparticle events. Furthermore, due to large...

We present the measurement of Wgamma and Zgamma production cross sections using data corresponding to the full 2010 and 2011 periods of the LHC run. For charged lepton decay modes of W and Z bosons the total cross sections are measured for photon transverse energy greater than 15 GeV. We also present the first measurement of Zgamma production cross section using the nunugamma final state for...

ATLAS has measured diboson production processes involving ZZ, WW, WZ, Wgamma and Zgamma. Visible cross sections are measured for channels involving leptons and neutrinos, and differentil distributions are presented. In the ZZ to 2l2nu and WW to lnulnu channels, jet vetos are applied. Total cross ections are derived, and limits are set on anomalous triple-gauge couplings.

Standard Model & Beyond
We present a measurement of the Drell Yan differential cross-section dsigma/dm, and the double differential cross section d^2sigma/dmdY in pp collisions at 7 TeV using a dataset corresponding to an integrated luminosity of 5 fb−1 recorded at the LHC with the CMS detector. The complete cross-section measurement is reported for both the di-muon and di-electron channels. The cross-section is...

Comprehensive measurements of inclusive and dijet cross sections are presented, spanning the dijet mass range from 70 GeV to 4 TeV. Inclusive photons and diphotons have also been measured over a wide range of mass and pT. These measurements constitute precision tests of QCD in a new energy regime, and show sensitivity to the parton densities in the proton. In addition, charged particles,...
