Efficient contraction of 1-loop N-point tensor integrals
Jochem Fleischer, Janusz Gluza, Marek Gluza +2
A new approach for the reduction of tensor integrals is described. The standard decomposition à la Davydychev is applied. Integrals with higher indices are then expressed in terms…
New developments in PJFry
Jochem Fleischer, Tord Riemann, Valery Yundin
We report on recent progress in numerical evaluation of one loop tensor integrals. A public C++ package PJFry implementing algorithms from arXiv:1009.4436 and its extension to hexa…
New results for algebraic tensor reduction of Feynman integrals
Jochem Fleischer, Tord Riemann, Valery Yundin
We report on some recent developments in algebraic tensor reduction of one-loop Feynman integrals. For 5-point functions, an efficient tensor reduction was worked out recently and…
