Higher-order one-loop contributions in Lorentz-breaking QED

Year: 2018

Type: article

Abstract: We calculate higher-order quantum contributions in different Lorentz-violating parameters to the gauge sector of the extended QED. As a result of this one-loop calculation, some terms which do not produce corrections of first order in Lorentz-breaking parameters, contribute with nontrivial gauge-invariant quantum corrections of second order in these parameters.
