Gustafson integrals for spin magnet
S. E. Derkachov, A. N. Manashov, P. A. Valinevich
It was observed recently that the multidimensional Mellin--Barnes integrals (Gustafson's integrals) arise naturally in studies of the spin chain models. We extend this an…
Spin Chains and Gustafson's Integrals
S. E. Derkachov, A. N. Manashov
Gustafson's integrals are multidimensional generalizations of the classical Mellin-Barnes integrals. We show that some of these integrals arise from relations between matrix elemen…
Higher-spin currents in the Gross-Neveu model at
A. N. Manashov, E. D. Skvortsov
We calculate the anomalous dimensions of higher-spin currents, both singlet and non-singlet, in the Gross-Neveu model at the order. It was conjectured that in the critical…
Two-loop conformal generators for leading-twist operators in QCD
V. M. Braun, A. N. Manashov, S. Moch +1
QCD evolution equations in minimal subtraction schemes have a hidden symmetry: One can construct three operators that commute with the evolution kernel and form an algebra,…
