Measurement of WW and WZ production with one vector boson decaying hadronically at ATLAS

Mostrar otras versiones (1)

A measurement by ATLAS of the combined WW and WZ cross-section in proton-proton collisions at the LHC at $\sqrt{s}=7$ TeV is presented, using 4.7 fb$^{-1}$ of data. The measurement is performed in the $\ell\nu$jj final state by fitting the di-jet invariant mass distribution. Evidence for WW/WZ produ...

description A measurement by ATLAS of the combined WW and WZ cross-section in proton-proton collisions at the LHC at $\sqrt{s}=7$ TeV is presented, using 4.7 fb$^{-1}$ of data. The measurement is performed in the $\ell\nu$jj final state by fitting the di-jet invariant mass distribution. Evidence for WW/WZ production is found at the 3.3 $\sigma$ level, and a cross-section of $\sigma(pp \to WW/WZ)=$ 72 $\pm$ 9 (stat.) $\pm$ 15 (syst.) $\pm$ 13 (Monte Carlo stat.) pb is measured, consistent with the Standard Model expectation.
