(06.07.) Iterated elliptic integrals: a canonical language for elliptic Feynman integrals
06.07.2017 at 16:15
While many Feynman integrals appearing in QCD can be evaluated using mulitple polylogarithms, there is a growing class of interesting integrals which do not fall into this class. After a short review, I will discuss the next interesting class: elliptic integrals. If evaluated, those yield elliptic multiple zeta values, a generalization of multiple zeta values. I will show that the canonical language - iterated integrals of modular forms - for investigating these elliptic integrals is provided by one-loop open string theory: here those integrals appear in the most pure setting.
