Abstract In this work we present a new method for the combination of electroweak (EW) corrections at high energies, the so-called EW Sudakov logarithms (EWSL), and next-to-leading-order QCD predictions matched to parton-shower simulations (NLO+PS). O

Abstract We present a new simulation for Higgs boson production in association with bottom quarks ( b b ¯ H $$ b\overline{b}H $$ ) at next-to-leading order (NLO) accuracy matched to parton showers in hadronic collisions. Both contributions, the stan

Abstract We present an update of the Universal FeynRules Output model format, commonly known as the UFO format, that is used by several automated matrix-element generators and high-energy physics software. We detail different features that have been

Abstract Within the framework of local analytic sector subtraction, we present the subtraction of next-to-leading-order QCD singularities for processes featuring massless coloured particles in the initial as well as in the final state. The features o

Abstract We compute the perturbative component of the fragmentation function of the b quark to the best of the present theoretical knowledge. The fixed-order calculation to order α s 2 $$ {\alpha}_s^2 $$ of the fragmentation function at the initial

Abstract In this work we revisit the algorithm of Denner and Pozzorini for the calculation of one-loop electroweak Sudakov logarithms and we automate it in the MadGraph5_aMC-@NLO framework. We adapt the formulas for modern calculations, keeping light

Abstract We study single top quark production in association with a WZ pair at the LHC in the context of the Standard Model (SM) and the Standard Model Effective Field Theory (SMEFT). A significant advantage of tWZ compared to other EW top production

Abstract In this work we compute for the first time the so-called Complete-NLO predictions for top-quark pair hadroproduction in association with at least one isolated photon (t t ¯ $$ \overline{t} $$ γ). We also compute NLO QCD+EW predictions for

Abstract We present MadFlow, a first general multi-purpose framework for Monte Carlo (MC) event simulation of particle physics processes designed to take full advantage of hardware accelerators, in particular, graphics processing units (GPUs). The au

Abstract The hadroproduction of a Higgs boson in association with a bottom-quark pair ( Hb b ¯ $$ Hb\overline{b} $$ ) is commonly considered as the key process for directly probing the Yukawa interaction between the Higgs boson and the bottom quark
