Shedding Light on Evanescent Shadows -- Exploration of non-anticommuting ${\hat{I}}_5^3$ in Dimensional Regularisation

Paul L. Ebert, Paul Kühler, Dominik Stöckinger +1

The mathematical consistency of the BMHV scheme of dimensional regularisation (DReg) comes at the cost of requiring symmetry-restoring counterterms to cancel the regularisation-ind…
