The two-loop sunrise graph in two space-time dimensions with arbitrary masses in terms of elliptic dilogarithms

Understand

We present the two-loop sunrise integral with arbitrary non-zero masses in two space-time dimensions in terms of elliptic dilogarithms.

• We find that the structure of the result is as simple and elegant as in the equal mass case, only the arguments of the elliptic dilogarithms are modified.
• These arguments have a nice geometric interpretation.
