Primordial Magnetic Fields and the Peccei-Quinn Scale
Leonardo Campanelli, Maurizio Giannotti
A strong primordial magnetic field can induce a relaxation of the present bound on the PQ-constant. We show that, considering the present limits on primordial magnetic fields, a va…

Magnetic Induced Axion Mass
L. Campanelli, M. Giannotti
We study the effect of a uniform magnetic field on the dynamics of axions. In particular, we show that the Peccei-Quinn symmetry is explicitly broken by the presence of an external…
