Non-abelian soft radiation data for a celestial theory
Lorenzo Magnea, Enrico Zunino
Celestial holography posits that the long-distance behavior of gauge and gravity theories is dictated by two-dimensional conformal field theories defined on the celestial sphere. F…
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…
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 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…
