On Ambiguities and Divergences in Perturbative Renormalization Group Functions
Florian Herren, Anders Eller Thomsen
There is an ambiguity in choosing field-strength renormalization factors in the scheme starting from the 3-loop order in perturbation theory. More concerni…
Constraints on 3- and 4-loop -functions in a general four-dimensional Quantum Field Theory
Colin Poole, Anders Eller Thomsen
The -functions of marginal couplings are known to be closely related to the -function through Osborn's equation, derived using the local renormalization group. It is possi…
Weyl Consistency Conditions and
C. Poole, A. E. Thomsen
The treatment of in Dimensional Regularization leads to ambiguities in field-theoretic calculations, of which one example is the coefficient of a particular term in the fou…
-theorem at large
Oleg Antipin, Nicola Andrea Dondi, Francesco Sannino +1
We determine the Jack and Osborn a-function and related metric for gauge-fermion theories to leading order in the large number of fermions and to all orders in the gauge coupling,…
