Bounds on Direct Couplings of Superheavy Metastable Particles to the Inflaton Field from Ultra High Energy Cosmic Ray Events
A. H. Campos, L. L. Lengruber, H. C. Reis +2
Top-down models for the origin of ultra high energy cosmic rays (UHECR's) propose that these events are the decay products of relic superheavy metastable particles, usually called…
