Abstract: A bstractRecently many investigations have considered Majorana dark matter co-annihilating with bound states formed by a strongly interacting scalar field. However only the gluon radiation contribution to bound state formation and dissociation, which at high… read more here.

Abstract: We present a novel source of dark energy, which is motivated by the prevalence of hidden sectors in string theory models and is consistent with all of the proposed swampland conjectures. Thermal effects hold a… read more here.

Abstract: We propose a mechanism of elementary thermal dark matter with a mass up to 10^{14} GeV, within a standard cosmological history, whose relic abundance is determined solely by its interactions with the standard model, without violating… read more here.

Abstract: We propose a new thermal freeze-out mechanism that results in dark matter masses exceeding the unitarity bound by many orders of magnitude, without violating perturbative unitarity or modifying the standard cosmology. The process determining the… read more here.
