Master Integrals for the mixed QCD-QED corrections to the Drell-Yan\n production of a massive lepton pair

We showcase the calculation of the master integrals needed for the two loop\nmixed QCD-QED virtual corrections to the neutral current Drell-Yan process\n$(q\\bar{q}\\rightarrow l^+ l^-)$. After establishing a basis of 51 master\nintegrals, we cast the latter into canonical form by using the Magnus\nalgorithm. The dependence on the lepton mass is then expanded such that\npotentially large logarithmic contributions are kept. After determining all\nboundary constants, we give the coefficients of the Taylor series around four\nspace-time dimensions in terms of generalized polylogarithms up to weight four.\n
