摘 要:We present the analytic calculation of two-loop master integrals that are relevant for tW production at hadron *** focus on the integral families with only one massive *** selecting a canonical basis,the differential equations for the master integrals can be transformed into the d In *** boundaries are determined by simple direct integrations or regularity conditions at kinematic points without physical *** analytical results in this work are expressed in terms of multiple polylogarithms,and have been checked via numerical computations.
