Forcer: parametric reduction of 4-loop massless propagators

Tuesday, 25 October 2016 at 11:15, in Y16 G05 - Campus Irchel

I will discuss techniques used in a new FORM program "Forcer" for
efficiently evaluating dimensionally regularized 4-loop massless
propagator-type Feynman integrals. The program implements parametric
reduction of the integrals and can be considered as an extension of the
"Mincer" program, but it required a lot of automatisations. I also
discuss physics results that can be obtained by use of Forcer.
