Towards mixed QCDxEW corrections to the charged-current Drell-Yan process with leptonic decay at high transverse masses

Christian Biello, Amlan Chakraborty, Giulio Gambuti +2

The Drell-Yan process is a key precision benchmark at the Large Hadron Collider and a sensitive probe of SM and SMEFT effects. Fully exploiting future LHC data requires percent-lev…

Two-loop all-plus helicity amplitudes for self-dual Higgs boson with gluons via unitarity cut constraints

Simon Badger, Christian Biello, Colomba Brancaccio +1

We present the two-loop amplitudes for a self-dual Higgs boson with up to four positive helicity gluons in the heavy top-quark limit. Because the tree amplitudes in the all-plus se…

Next-to-next-to-leading order event generation for production with approximate two-loop amplitude

Christian Biello, Chiara Savoini, Chiara Signorile-Signorile +1

We study Higgs-boson production in association with a top-quark pair () at hadron colliders and present the first matching of next-to-next-to-leading order (NNLO) QCD co…

Modelling production for the LHC at 13.6 TeV

Christian Biello, Alessandro Gavardi, Rebecca von Kuk +10

We present new state-of-the-art predictions for Standard Model Higgs boson production in association with a bottom-quark pair (). Updated cross sections are computed in a…

Higgs boson production in association with massive bottom quarks at NNLO+PS

Christian Biello, Javier Mazzitelli, Aparna Sankar +2

We study the production of a Higgs boson in association with a bottom-quark pair () at hadron colliders. Our calculation is performed in the four-flavour scheme with ma…

Time-Like Heavy-Flavour Thresholds for Fragmentation Functions: the Light-Quark Matching Condition at NNLO

Christian Biello, Leonardo Bonino

Matching conditions are universal ingredients that describe how fragmentation functions change when heavy-flavour thresholds are crossed during the factorisation scale evolution. T…
