Description
In the standard model (SM), the top quark is a very special particle. Because its mass is much larger than any other SM elementary particles, the top quark is speculated to play a special role in electroweak symmetry breaking (EWSB). With its unique properties has long been believed of potentially carrying important information to solve some of the paramount open questions in particle physics. So, precise measurements of the cross sections and properties of top quark production channels are significant. With the measurement of the cross section of top quark pairs production in association with a photon (Higgs boson) , the strength of the electromagnetic (Yukawa) coupling of the top quark can be probed directly. The precision predicts for $t\bar t \gamma$/$t\bar t H$ production are necessary to meet requirements of the experimental measurement. In this talk, the next-to-leading (NLO) electroweak (EW) corrections to $t\bar t \gamma$/$t\bar t H$ production at LHC and further hadron colliders will be present.
