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 and dimensions. The amplitude is expressed in terms of a set of Feynman…

Analysis of and -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.…
