We calculate the next-to-next-to-leading order (NNLO) QED virtual and soft corrections to the C -odd part of the differential cross section of the e + e − → μ + μ − process. This part contributes to the angular and forward-backward asymmetry. Together with our earlier paper [1], this work completes the analytical calculation of e + e − → μ + μ − differential cross section at NNLO.
