Abstract With the goal of increasing the precision of NLO QCD predictions for the pp → t t ¯ γ $$ pp\to t\overline{t}\gamma $$ process in the di-lepton top quark decay channel we present theoretical predictions for the ℛ = σ t t ¯ γ / σ t t

Abstract We present a complete description of top quark pair production in association with a hard photon in the dilepton channel. Our calculation is accurate to NLO in QCD. It is based on matrix elements for e + ν e μ − ν ¯ μ b b ¯ γ $$ {e}

Abstract A precise measurement of the top quark mass, a fundamental parameter of the Standard Model, is among the most important goals of top quark studies at the Large Hadron Collider. Apart from the standard methods, numerous new observables and re

We compute the two-loop QCD helicity amplitudes for the production of a Higgs boson in association with a bottom-quark pair at a hadron collider. We take the approximations of leading colour and work in the five flavour scheme, where the bottom quark

Recent discrepancies between theoretical predictions and experimental data in multi-lepton plus $b$-jets analyses for the $t\bar{t}W^\pm$ process, as reported by the ATLAS collaboration, have indicated that more accurate theoretical predictions and h

We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic form of the finite remainders from numerical evaluations over finite fields

Recent measurements of the pp → t t ¯ W ± $$ t\overline{t}{W}^{\pm } $$ process in multi-lepton final states, as performed by the ATLAS collaboration in the context of the Higgs boson studies in the t t ¯ H $$ t\overline{t}H $$ channel, have sho

Triggered by ongoing dark matter searches in the top quark sector at the Large Hadron Collider we report on the calculation of the next-to-leading order QCD corrections to the Standard Model process pp → t$$ \overline{t} $$ t ¯ + Z (Z → νℓ$$
