Regularization techniques for the radiative corrections of Wilson lines and Kaluza-Klein states
Physical Review D
Within an effective field theory framework we compute the most general structure of the one-loop corrections to the 4D gauge couplings in one- and two-dimensional orbifold compactifications with non-vanishing constant gauge background (Wilson lines). Although such models are non-renormalisable, we keep the analysis general by considering the one-loop corrections in three regularisation schemes: dimensional regularisation (DR), Zeta-function regularisation (ZR) and proper-time cut-offdoi:10.1103/physrevd.70.045011 fatcat:izugzh55ingyvmxvagbzandu3a
