The $q$ -extension of iterated integrals and nested sums in quantum field theory

J. BlÃ¼mlein, J. Blümlein, A. M. Gavrilik +2

Analytic calculations of zero- and single-scale quantities in perturbative quantum field theory result into special numbers and functions, the first of which have been revealed dur…

The two-mass contributions to the three-loop massive operator matrix elements $A ~_{Q g}^{(3)}$ and $I^ A ~_{Q g}^{(3)}$

J. Ablinger, J. BlÃ¼mlein, A. De Freitas +3

We calculate the two-mass three-loop contributions to the unpolarized and polarized massive operator matrix elements $A ~_{Q g}^{(3)}$ and $I^ A ~_{Q g}^{(3)}$ in $x$ -spac…
