NLO QCD predictions for t t ¯ γ $$ t\overline{t}\gamma $$ with realistic photon isolation by Daniel Stremmer, Malgorzata Worek

“…We provide the results for the pp → e + ν e μ − ν ¯ b b ¯ γ $$ {e}^{+}{\nu}_e\ {\mu}^{-}\ \overline{\nu}\ b\overline{b}\ \gamma $$ + X process using the fixed-cone, smooth-cone and hybrid-photon isolation criteria. The fixed-cone isolation criterion allows contributions from collinear photon radiation off QCD partons, which requires the inclusion of parton-to-photon fragmention processes. …”
