General massive one-loop off-shell three-point functions
In this work we compute the most general massive one-loop off-shell three-point vertex in D-dimensions, where the masses, external momenta, and exponents of propagators are arbitrary. This follows our previous paper in which we have calculated several new hypergeometric series representations for massless and massive (with equal masses) scalar one-loop three-point functions, in the negative dim...
متن کاملNegative dimensional approach for scalar two-loop three-point and three-loop two-point integrals
The study of quantum field theories in the perturbative regime can sometimes become a very challenging and arduous issue to deal with, especially when one needs to go on calculating multi-loop Feynman integrals. There are several techniques that have been developed and refined in the course of time, but usually the calculations are rather involved and analytic results are difficult to obtain. D...
متن کاملTwo - loop off - shell QCD amplitudes in FDR
We link the FDR treatment of ultraviolet (UV) divergences to dimensional regularization up to two loops in QCD. This allows us to derive the one-loop and two-loop coupling constant and quark mass shifts necessary to translate infrared finite quantities computed in FDR to the MS renormalization scheme. As a by-product of our analysis, we solve a problem analogous to the historical difficulties o...
متن کاملTwo - loop sunset diagrams with three massive lines
In this paper, we consider the two-loop sunset diagram with two different masses, m and M , at spacelike virtuality q2 = −m2. We find explicit representations for the master integrals and an analytic result through O(ε) in d = 4 − 2ε space-time dimensions for the case of equal masses, m = M . PACS: 11.15.-q, 12.38.Bx
متن کاملTwo-loop helicity amplitudes for the production of two off-shell electroweak bosons in gluon fusion
We compute the part of the two-loop virtual amplitude for the process gg → V1V2 → (l1 l̄ ′ 1)(l2 l̄ ′ 2), where V1,2 are arbitrary electroweak gauge bosons, that receives contributions from loops of massless quarks. Invariant masses of electroweak bosons are allowed to be different from each other. Our result provides an important ingredient for improving the description of gluon fusion contribut...
