DOI: 10.1007/jhep02(2022)136
Abstract: Abstract Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory. Their exact evaluation requires numerical integrals over anomalous dimensions, which in… read more here.
