On non-factorisable contributions to -channel single-top production
arXiv:2108.09222 · doi:10.1007/JHEP11(2021)130
Abstract
We compute the non-factorisable contribution to the two-loop helicity amplitude for -channel single-top production, the last missing piece of the two-loop virtual corrections to this process. Our calculation employs analytic reduction to master integrals and the auxiliary mass flow method for their fast numerical evaluation. We study the impact of these corrections on basic observables that are measured experimentally in the single-top production process.
