(Un)determined finite regularization dependent quantum corrections: the Higgs decay into two photons and the two photon scattering examples
A. L. Cherchiglia, L. A. Cabral, M. C. Nemes +1
We investigate the appearance of arbitrary, regularization dependent parameters introduced by divergent integrals in two a priori finite but superficially divergent amplitudes: the…

Ambiguities in the gravitational correction of quantum electrodynamics
J. C. C. Felipe, L. A. Cabral, L. C. T. Brito +2
We verify that quadratic divergences stemming from gravitational corrections to QED which have been conjectured to lead to asymptotic freedom near Planck scale are arbitrary (regul…
