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…
Physics Briefing Book: Input for the 2026 update of the European Strategy for Particle Physics
Jorge de Blas, Monica Dunford, Emanuele Bagnaschi +127
The European Strategy for Particle Physics (ESPP) reflects the vision and presents concrete plans of the European particle physics community for advancing human knowledge in fundam…
Refactorisation and Subtraction
Lorenzo Magnea, Calum Milloy, Chiara Signorile-Signorile +1
Infrared subtraction algorithms beyond next-to-leading order necessitate the analysis of multiple infrared limits of scattering amplitudes, where several particles sequentially bec…
Strongly-ordered infrared counterterms from factorisation
Lorenzo Magnea, Calum Milloy, Chiara Signorile-Signorile +1
In the context of infrared subtraction algorithms beyond next-to-leading order, it becomes necessary to consider multiple infrared limits of scattering amplitudes, in which several…
A fresh look at the nested soft-collinear subtraction scheme: NNLO QCD corrections to -gluon final states in annihilation
Federica Devoto, Kirill Melnikov, Raoul Röntsch +2
We describe how the nested soft-collinear subtraction scheme [1] can be used to compute the next-to-next-to-leading order (NNLO) QCD corrections to the production of an arbitrary n…
Advances in the nested soft-collinear subtraction scheme
Chiara Signorile-Signorile, Davide Maria Tagliabue
We discuss a path toward the generalisation of the nested soft-collinear subtraction scheme to arbitrary processes. The scheme is designed to provide an efficient…
NNLO subtraction for any massless final state: a complete analytic expression
Gloria Bertolotti, Lorenzo Magnea, Giovanni Pelliccioli +4
We use the Local Analytic Sector Subtraction scheme to construct a completely analytic set of expressions implementing a fully local infrared subtraction at NNLO for generic colour…
Strongly-ordered infrared limits for subtraction counterterms from factorisation
Lorenzo Magnea, Calum Milloy, Chiara Signorile-Signorile +2
After a brief introduction to the problem of subtraction of infrared divergences for high-order collider observables, we present a preliminary study of strongly-ordered soft and co…
Non-factorisable contributions to -channel single-top production at the LHC and FCC
Christian Brønnum-Hansen, Jérémie Quarroz, Chiara Signorile-Signorile +1
Single top quark is mainly produced through the -channel W boson exchange at LHC. This process probes Wtb vertex directly and can be used to measure t…
Non-factorisable contribution to -channel single-top production
Christian Brønnum-Hansen, Kirill Melnikov, Jérémie Quarroz +2
We compute the non-factorisable corrections to -channel single-top quark production at the LHC. These peculiar corrections arise because of interactions betwee…
Mixed QCD-electroweak corrections to dilepton production at the LHC in the high invariant mass region
Federico Buccioni, Fabrizio Caola, Herschel A. Chawdhry +6
We compute mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons in the high invariant mass region. Our computation is fully d…
The Infrared Structure of Perturbative Gauge Theories
Neelima Agarwal, Lorenzo Magnea, Chiara Signorile-Signorile +1
Infrared divergences in the perturbative expansion of gauge theory amplitudes and cross sections have been a focus of theoretical investigations for almost a century. New insights…

W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
Analytic integration of soft and collinear radiation in factorised QCD cross sections at NNLO
Lorenzo Magnea, Giovanni Pelliccioli, Chiara Signorile-Signorile +2
Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD…
