Two-loop master integrals for pseudo-scalar quarkonium and leptonium production and decay

Two-loop master integrals for pseudo-scalar quarkonium and leptonium production and decay

Abstract We compute the master integrals relevant for the two-loop corrections to pseudo-scalar quarkonium and leptonium production and decay. We present both analytic and high-precision numerical results. The analytic expressions are given in terms of multiple polylogarithms (MPLs), elliptic multip...
