Towards numerical two-loop integrand reduction

Giuseppe Bevilacqua, Dhimiter Canko, Costas Papadopoulos +1

We present a method for the integrand-level reduction of two-loop helicity amplitudes in both $d = 4 - 2 ε$ and $d = 4$ dimensions. The amplitude is expressed in terms of a set of Feynman…

Analysis of $(n + 1)$ and $n$ -parton contributions for computing QCD jet cross sections in the local analytic subtraction scheme

Bakar Chargeishvili, Giuseppe Bevilacqua, Adam Kardos +2

We analyze and implement the Local Analytic Sector Subtraction (LASS) scheme for handling infrared singularities in next-to-next-to-leading order (NNLO) calculations in perturbativ…

LASS, the numerics

Adam Kardos, Giuseppe Bevilacqua, Bakar Chargeishvili +2

We summarize our efforts to create a numerical implementation of the Local Analytical Subtraction Scheme (LASS) for obtaining NNLO QCD predictions in electron-positron collisions.…
