Five-loop additive renormalization in the phi^4 theory and amplitude functions of the minimally renormalized specific heat in three dimensions
S. A. Larin, M. Moennigmann, M. Stroesser +1
We present an analytic five-loop calculation for the additive renormalization constant A(u,epsilon) and the associated renormalization-group function B(u) of the specific heat of t…
The 4-loop quark mass anomalous dimension and the invariant quark mass
J. A. M. Vermaseren, S. A. Larin, T. van Ritbergen
We present the analytical calculation of the four-loop quark mass anomalous dimension in Quantum Chromodynamics within the minimal subtraction scheme. On the basis of this result w…
The (alpha_s)^3 approximation of Quantum Chromodynamics to the Ellis-Jaffe sum rule
S. A. Larin, T. van Ritbergen, J. A. M. Vermaseren
We present the analytical calculation in perturbative Quantum Chromodynamics of the (alpha_s)^3 contribution to the Ellis-Jaffe sum rule for the structure function g1 of polarized…
The four-loop beta-function in Quantum Chromodynamics
T. van Ritbergen, J. A. M. Vermaseren, S. A. Larin
We present the analytical calculation of the four-loop QCD beta-function within the minimal subtraction scheme.
