Tensor Two-loop Self-energy Integrals

Phan Hong Khiem, Do Hoang Son


Based on the technique for evaluating tensor two-loop self-energy  integrals in parallel and orthogonal spaces \cite{kreimer94}, we present a new UV subtraction procedure for  a subset of integrals which contains overall UV-divergence. The numerical and analytical results of the sun-rise integral are discussed in comparison with other methods.
