Top-Yukawa contributions to bbH production at the LHC
Journal of High Energy Physics, 2019 We study the production of a Higgs boson in association with bottom quarks b b ¯ H $$ \left(b\overline{b}H\right) $$ in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa ...

Multi-jet production in lepton-proton scattering at next-to-leading order accuracy
, 2005 I summarize the theoretical and experimental status of multijet production in DIS. I present the state of the art theoretical predictions and compare those to the corresponding experimental results obtained by analysing the data collected by the H1 and ...

Numerical integration of loop integrals through local cancellation of threshold singularities
Journal of High Energy Physics, 2022 We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is given by the Loop-Tree Duality integral supplemented with suitable ...

Hadroproduction of $W^+ W^- b \bar{b}$ at NLO accuracy matched with shower Monte Carlo programs
, 2014 We present the computation of the differential cross section for the process $pp(\bar{p}) \to (W^+\,W^-\,b\,\bar{b} \to)\;e^+\,\nu_e\,\mu^-\,\bar{\nu}_\mu\,b\, \bar{b}+X$ at NLO QCD accuracy matched to Shower Monte Carlo (SMC) simulations using PowHel ...

Automation of electroweak corrections for LHC processes [PDF]
, 2015 For the Run 2 of the LHC next-to-leading order electroweak corrections will play an important role. Even though they are typically moderate at the level of total cross sections they can lead to substantial deviations in the shapes of distributions.

Geometric IR subtraction for final state real radiation
Journal of High Energy Physics, 2018 A scheme is proposed for the subtraction of soft and collinear divergences present in massless final state real emission phase space integrals. The scheme is based on a local slicing procedure which utilises the soft and collinear factorisation ...

High multiplicity processes at NLO with BlackHat and Sherpa
, 2012 In this contribution we review recent progress with fixed-order QCD predictions for the production of a vector boson in association with jets at hadron colliders, using the programs BlackHat and SHERPA. We review general features of next-to-leading-order

Full one-loop amplitudes from tree amplitudes [PDF]
, 2008 We establish an efficient polynomial-complexity algorithm for one-loop calculations, based on generalized $D$-dimensional unitarity. It allows automated computations of both cut-constructible {\it and} rational parts of one-loop scattering amplitudes ...
