Abstract

We present the results for two-loop massive kite master integrals with elliptics in terms of iterated in-tegrals with algebraic kernels. The key ingredients are new integral representations for sunset subgraphs in d=4 −2εand d=2 −2εdimensions together with differential equations for considered kite master integrals in A +Bεform. The obtained results can be easily generalized to all orders in ...
