Abstract In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the Geneva framework and working in the heavy-top-limit approximation. This includes the resummation of large

Abstract We describe a number of improvements to the Geneva method for matching NNLO calculations to parton shower programs. In particular, we detail changes to the resummed calculation used in the matching procedure, including disentangling the cros

Abstract We consider the production of a pair of Z bosons at the LHC and study the inclusion of EW corrections in theoretical predictions at fixed order and based on multijet-merged parton-shower simulations. To this end we present exact NLO EW resul

Abstract We present a new calculation for the production of isolated photon pairs at the LHC with NNLL T 0 ′ $$ {\mathrm{NNLL}}_{{\mathcal{T}}_0}^{\prime } $$ +NNLO accuracy. This is the first implementation within the Geneva Monte Carlo framework

Abstract We present the NNLL′ resummed 2-jettiness distribution for decays of the Standard Model Higgs boson to a b b ¯ $$ \overline{b} $$ -quark pair and to gluons. The calculation exploits a factorisation formula derived using Soft-Collinear Eff

Abstract We present an automated implementation for the calculation of one-loop double and single Sudakov logarithms stemming from electroweak radiative corrections within the SHERPA event generation framework, based on the derivation in Denner and P

We present a novel next-to-next-to-leading order (NNLO) QCD calculation matched to parton shower for the production of a pair of Z bosons decaying to four massless leptons, pp→ℓ+ℓ−ℓ′+ℓ′−+X, at the LHC. Spin correlations, interferenc

We compute the total cross-section for Higgs boson production in bottom-quark fusion using the so-called FONLL method for the matching of a scheme in which the b-quark is treated as a massless parton to that in which it is treated as a massive final-

Abstract We show that a simple and accurate approach to the computation of hadron collider processes involving initial-state b quarks can be obtained by introducing an independently parametrized b PDF. We use the so-called FONLL method for the matchi

Abstract Jet substructure tools have proven useful in a number of high-energy particle-physics studies. A particular case is the discrimination, or tagging, between a boosted jet originated from an electroweak boson (signal), and a standard QCD parto
