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…

Tree level Leptogenesis from Kalb-Ramond Torsion Background
M. de Cesare, Nick E. Mavromatos, Sarben Sarkar
The effect of torsion in theories of quantum gravity is known to be well described by an axion-like field which couples to matter as well as to gravitation and radiation gauge fiel…

Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
J. Albert et al., John Ellis, N. E. Mavromatos +3
We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some…
