Three-loop effective potential from differential equations

Presented by Dr. Andrey PIKELNER
Type: Oral
Track: Theoretical Physics

Content

We present calculation of the three-loop effective potential in massive scalar theory in broken phase. The calculation involves evaluation of three-loop vacuum integrals with two different masses. Full set of integrals evaluated analytically using a system of differential equations in canonical form and expressed in terms of cyclotomic polylogarithms.
