Two-loop master integrals for $e^{+} e^{-} \to μ^{+} μ^{-}$ process with account of electron mass

Roman N. Lee

We calculate a subset of two-loop master integrals relevant for the differential cross section of $e^{+} e^{-} \to μ^{+} μ^{-}$ process. We consider only those families for which the account…

Master integrals for $e^{+} e^{-} \to 2 γ$ process at large energies and angles

Roman N. Lee, Vyacheslav A. Stotsky

We calculate two-loop massive master integrals for $e^{+} e^{-} \to 2 γ$ in terms of generalized power series with respect to electron mass. The coefficients of this series are…

Polylogarithmic functions with prescribed branching locus and linear relations between them

Roman N. Lee

We consider the problem of finding the set of classical polylogarithmic functions $Li_{n}$ with branching locus determined by the solution of $p_1\cdot p_2\cdot \ldots \cdot p…
