On series and integral representations of some NRQCD master integrals
M. A. Bezuglov, A. V. Kotikov, A. I. Onishchenko
We consider new ways of obtaining series and integral representations for master integrals arising in the process of matching of QCD to NRQCD. The latter results are exact in space…
Non-planar elliptic vertex
M. A. Bezuglov, A. I. Onishchenko
We consider the problem of obtaining higher order in regularization parameter analytical results for master integrals with elliptics. The two commonly employed methods are prov…
Two-loop sunset diagrams with three massive lines
B. A. Kniehl, A. V. Kotikov, A. Onishchenko +1
In this paper, we consider the two-loop sunset diagram with two different masses, m and M, at spacelike virtuality q^2 = -m^2. We find explicit representations for the master integ…
Nonforward anomalous dimensions of Wilson operators in N=4 super-Yang-Mills theory
A. I. Onishchenko, V. N. Velizhanin
We present the next-to-leading order results for universal non-forward anomalous dimensions of Wilson twist-2 operators in N=4 supersymmetric Yang-Mills theory. The whole calculati…
