Schwinger-Dyson equations and mass generation for an axion theory with a PT symmetric Yukawa fermion interaction
N. E. Mavromatos, Sarben Sarkar, A. Soto
A nonperturbative Schwinger-Dyson analysis of mass generation is presented for a non-Hermitian PT-symmetric field theory in four dimensions of an axion coupled to a Dirac fermion.T…
Induced non-Abelian Chern-Simons effective action in very special relativity
Z. Haghgouyan, M. Ghasemkhani, R. Bufalo +1
In this paper, we study the one-loop induced effective action for a non-abelian gauge field in the very special relativity (VSR) framework in a -dimensional spacetime. We sh…
Cosmology in the presence of diffeomorphism-violating, nondynamical background fields
Carlos M. Reyes, Marco Schreck, Alex Soto
We consider diffeomorphism violation, which is parameterized by nondynamical background fields of the gravitational Standard-Model Extension (SME), and study its effects on the tim…
Impossibility of obtaining a CP-violating Euler-Heisenberg effective theory from a viable modification of QED
M. Ghasemkhani, V. Rahmanpour, R. Bufalo +1
In this paper, we examine the CP-violating term of the Euler-Heisenberg action. We focus in the aspects related with the generation of such a term from a QED-like model in terms of…
