Description
We present the calculation of the master integrals needed for the two loop mixed QCD-Electroweak virtual corrections to the neutral current Drell-Yan processes $(q\bar{q}\rightarrow l^+ l^-)$. The dependence on the lepton mass is expanded such that potentially large logarithmic contributions are kept. Finally, the canonical master integrals are given as a Taylor series around four space-time dimensions with coefficients given in terms of generalized polylogarithms up to weight four.
