Advances in Local Analytic Sector Subtraction: massive NLO and elements of NNLO automation
Gloria Bertolotti, Giovanni Limatola, Paolo Torrielli +1
In this article we present a number of developments within the scheme of Local Analytic Sector Subtraction for infrared divergences in QCD. First, we extend the scheme to deal with…
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…
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…
Local analytic sector subtraction for initial- and final-state radiation at NLO in massless QCD
Gloria Bertolotti, Paolo Torrielli, Sandro Uccirati +1
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…
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…
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…
Local analytic sector subtraction for final state radiation at NNLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We present recent developments of the local analytic sector subtraction of infrared singularities for final state real radiation at NNLO in QCD.
Factorisation and Subtraction beyond NLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We provide a general method to construct local infrared subtraction counterterms for unresolved radiative contributions to differential cross sections, to any order in perturbation…
Local Analytic Sector Subtraction at NNLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We present a new method for the local subtraction of infrared divergences at next-to-next-to-leading order (NNLO) in QCD, for generic infrared-safe observables. Our method attempts…
Factorization and subtraction
Lorenzo Magnea, Ezio Maina, Paolo Torrielli +1
We explore the connection between the factorisation of virtual corrections to multi-particle massless gauge theory amplitudes and the problem of subtraction at NNLO and beyond. Tak…
Towards analytic local sector subtraction at NNLO
Lorenzo Magnea, Ezio Maina, Paolo Torrielli +1
A new method for local subtraction at next-to-next-to-leading order in QCD is sketched, attempting to conjugate the minimal counterterm structure arising from a sector partition of…
