Nonthermal production of dark matter from a late-decaying scalar field at an intermediate scale

Journal Article Endo, Motoi ; Takahashi, Fuminobu ; Institute for Cosmic Ray Research, University of Tokyo, Chiba 277-8582 - Physical Review. D, Particles Fields

We examine nonthermal dark matter production from a late-decaying scalar field, with a particular attention on nonrenormalizable operators of D=5 through which the scalar field decays into the standard model particles and their superpartners. We show that almost the same number of superparticles as that of particles are generally produced from the decay. To avoid the gravitino overproduction problem, the decay is favored to proceed via interactions with an intermediate cutoff scale M<<M{sub P}. This should be contrasted to the conventional scenario using the modulus decay. The saxion, a scalar partner of the axion, is proposed as a natural candidatemore »« less

Recommendations of the LHC Dark Matter Working Group: Comparing LHC searches for dark matter mediators in visible and invisible decay channels and calculations of the thermal relic density

Journal Article Albert, Andreas ; Backović, Mihailo ; Boveia, Antonio ; ... - Physics of the Dark Universe

Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, the LHC would produce dark matter through these mediators, leading to the familiar "mono-X" search signatures, but the mediators would also produce signals without missing momentum via the same vertices involved in their production. This document from the LHC Dark Matter Working Group suggests how to compare searches for these two types of signals in case of vector and axial-vector mediators, based on a workshop that took place on September 19/20, 2016 and subsequent discussions. These suggestions include how to extend the spin-1 mediated simplifiedmore »« less

Astrophysical implications of a visible dark matter sector from a custodially warped GUT

Journal Article Agashe, Kaustubh ; Blum, Kfir ; Lee, Seung J ; ... - Physical Review. D, Particles Fields

We explore, within the warped extra dimensional framework, the possibility of finding antimatter signals in cosmic rays (CRs) from dark matter (DM) annihilation. We find that exchange of order 100 GeV radion, an integral part of this class of models, generically results in a sizable Sommerfeld enhancement of the annihilation rate for DM mass at the TeV scale. No ad hoc dark sector is required to obtain boosted annihilation cross sections and hence signals. Such a mild hierarchy between the radion and DM masses can be natural due to the pseudo-Goldstone boson nature of the radion. We study the implicationsmore »« less
