Measurement of the semileptonic t\overline{t} + γ production cross section in pp collisions at √{s}=8 TeV
A measurement of the cross section for top quark-antiquark ( t\overline{t} ) pairs produced in association with a photon in proton-proton collisions at √{s}=8 TeV is presented. The analysis uses data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.7 fb1. The signal is defined as the production of a t
