Planck-Scale Effects on Global Symmetries: Cosmology of Pseudo-Goldstone Bosons
Eduard Masso, Francesc Rota, Gabriel Zsembinszki
We consider a model with a small explicit breaking of a global symmetry, as suggested by gravitational arguments. Our model has one scalar field transforming under a non-anomalous…

On Axion Thermalization in the Early Universe
Eduard Masso, Francesc Rota, Gabriel Zsembinszki
We reanalyze the conditions under which we have a primordial thermal population of axions. Compared with previous studies, we find other processes, involving gluons and quarks, tha…

Neutrino-photon reactions for energies above
Eduard Masso, Francesc Rota
We show that neutrino-photon reactions above are dominated by the reaction . We calculate its cross-section and see that it is larger by several orders of mag…
