Description
We present analytic expressions for the two-loop planar master integrals for charged current Drell-Yan production of massless electron-positron pair through bottom-antibottom annihilation channel. We find two additional planar topologies over the topologies in the four-flavor scheme where the top quark is present as an internal line, i.e., double-box and penta-triangle topologies. The double-box topology has 46 master integrals, while the penta-triangle one has 44 master integrals. We use the method of differential equations to obtain analytical expression of the master integrals.
