The axion shield
A. Andrianov, D. Espriu, F. Mescia +1
We investigate the propagation of a charged particle in a spatially constant, but time dependent, pseudoscalar background. Physically this pseudoscalar background could be provided…
Anomalous positron excess from Lorentz-violating QED
Alexander A. Andrianov, Domenec Espriu, Paola Giacconi +1
We entertain the idea that a suitable background of cold (very low momentum) pseudoscalar particles or condensate, may trigger a background that effectively generates Lorentz-invar…
Spontaneous P-violation in QCD in extreme conditions
A. A. Andrianov, V. A. Andrianov, D. Espriu
We investigate the possibility of parity being spontaneously violated in QCD at finite baryon density and temperature. The analysis is done for an idealized homogeneous and infinit…
Bare and Induced Lorentz and CPT Invariance Violations in QED
J. Alfaro, A. A. Andrianov, M. Cambiaso +2
We consider QED in a constant axial vector background (Æther). Further Lorentz invariance violations (LIV) might occur owing to radiative corrections. The phenomenology of this mod…
