PT symmetric fermionic field theories with axions: Renormalization and dynamical mass generation
N. E. Mavromatos, Sarben Sarkar, A. Soto
We consider the renormalisation properties of non-Hermitian Yukawa theories involving a pseudoscalar (axion) field at or near dimensions. The non-Hermiticity is \cPT-symmetric…

Induced CP-violation in the Euler-Heisenberg Lagrangian
M. Ghasemkhani, V. Rahmanpour, R. Bufalo +2
In this paper, we examine the behaviour of the Euler-Heisenberg effective action in the presence of a novel axial coupling among the gauge field and the fermionic matter. This axia…
