Towards a new approximation for pair-production and associated-production of the Higgs boson
Xiaofeng Xu, Li Lin Yang
We propose that loop integrals with internal heavy particles can be evaluated by expanding in the limit of small external masses. This provides a systematically improvable approxim…

The next-to-next-to-leading order soft function for top quark pair production
Guoxing Wang, Xiaofeng Xu, Li Lin Yang +1
We present the first calculation of the next-to-next-to-leading order threshold soft function for top quark pair production at hadron colliders, with full velocity dependence of th…
