NNLO soft function for top quark pair production at small transverse momentum

Abstract The cross section for top quark pair production factorizes at small transverse momentum of the heavy quark pair, q T . One of the key ingredients that appears in the factorization formula is the soft function, which mediates soft gluon exchanges between particles and gives rise to colour co...
