Journal of High Energy Physics, 2019 We complete the analytic evaluation of the master integrals for the two-loop non-planar box diagrams contributing to the top-pair production in the quark-initiated channel, at next-to-next-to-leading order in QCD.

Constructing d-log integrands and computing master integrals for three-loop four-particle scattering
Journal of High Energy Physics, 2020 We compute all master integrals for massless three-loop four-particle scattering amplitudes required for processes like di-jet or di-photon production at the LHC.

Thermal dilepton production from hot QCD
, 2015 NLO and LPM-resummed computations of thermal dilepton production from a hot QCD plasma are reviewed. An interpolation applicable for all positive photon invariant masses is presented, and possibilities for comparisons with lattice and experimental data ...

Top quark pair production in association with a jet with NLO parton showering [PDF]
, 2011 We compute the production cross section of a top-antitop pair in association with a jet at hadron colliders at next-to-leading order accuracy matched with parton shower algorithms to make predictions at the hadron level.

Two-loop perturbative corrections to the constrained effective potential in thermal QCD
Journal of High Energy Physics, 2019 In this paper, we compute the constrained QCD effective potential up to two-loop order with finite quark mass and chemical potential. We present the explicit calculations by using the double line notation and analytical expressions for massless quarks ...

Two-loop splitting in double parton distributions: the colour non-singlet case
Journal of High Energy Physics, 2021 At small inter-parton distances, double parton distributions receive their dominant contribution from the splitting of a single parton. We compute this mechanism at next-to-leading order in perturbation theory for all colour configurations of the ...

NLO electroweak corrections in extended Higgs Sectors with RECOLA2 [PDF]
, 2017 We present the computer code RECOLA2 along with the first NLO electroweak corrections to Higgs production in vector-boson fusion and updated results for Higgs strahlung in the Two-Higgs-Doublet Model and Higgs-Singlet extension of the Standard Model.

Top-quark mass effects in double and triple Higgs production in gluon-gluon fusion at NLO [PDF]
, 2014 The observation of double and triple scalar boson production at hadron colliders could provide key information on the Higgs self couplings and the potential.

From dimensional regularization to NLO computations in four dimensions
, 2015 Loop-tree duality (LTD) allows to express virtual contributions in terms of phase-space integrals, thus leading to a direct mapping with real radiation terms. We review the basis of the method and describe its application to regularize Feynman integrals.

Matching NLO QCD and parton showers in heavy flavour production [PDF]
, 2003 We apply the MC@NLO approach to the process of heavy flavour hadroproduction. MC@NLO is a method for matching next-to-leading order (NLO) QCD calculations and parton shower Monte Carlo (MC) simulations, with the following features: fully exclusive events
