Effective Field Theory for ttγ at √s = 13 TeV — •Binish Batool1, Carmen Diez Pardos2, and Ivor Fleck3 for the ATLAS collaboration — 1binish.batool@cern.ch — 2carmen.diez.pardos@cern.ch — 3fleck@hep.physik.uni-siegen.de
The cross section measurement for the production of top anti-top quark pair in association with a photon (ttγ) probes the electroweak coupling of top quark and photon. The high energy and luminosity of LHC data could provide an opportunity to look for possible deviations from the standard model (SM). These deviations are interpreted by employing model dependent and model independent, such as Effective Field Theory, approaches. This talk is about the later one, where three, dimension-six operators, namely OtG, OtB, OtW are investigated. The sensitivity of the total and differential ttγ cross sections towards these operators, is investigated and expected limits for the full run2 data at √s = 13 TeV, on the operators are given.
