Boosted dark matter from semi-annihilations in the galactic center
Boris Betancourt Kamenetskaia, Motoko Fujiwara, Alejandro Ibarra +1
In some scenarios, the dark matter relic abundance is set by the semi-annihilation of two dark matter particles into one dark matter particle and one Standard Model particle. These…
Phenomenology of a scotogenic neutrino mass model at 3-loops
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +3
By extending the minimal scotogenic model with a spontaneously broken global symmetry and a preserved symmetry, we build a seesaw model for generating neutri…
Simultaneous detection of boosted dark matter and neutrinos from the semi-annihilation at DUNE
Mayumi Aoki, Takashi Toma
Dark matter direct detection experiments impose the strong bounds on thermal dark matter scenarios. The bound can naturally be evaded if the cross section is momentum transfer or v…
Phantom fluid cosmology: Impact of a phantom hidden sector on cosmological observables
James M. Cline, Matteo Puel, Takashi Toma +1
Phantom scalar theories are widely considered in cosmology, but rarely at the quantum level, where they give rise to negative-energy ghost particles. These cause decay of the vacuu…
Boosted dark matter from a phantom fluid
James M. Cline, Matteo Puel, Takashi Toma
It is known that theories of phantom dark energy, considered as quantum fields, predict a continuous production of positive- plus negative-energy particles, from spontaneous decay…
Sterile neutrino dark matter: relativistic freeze-out
Oleg Lebedev, Takashi Toma
Long-lived sterile neutrinos can play the role of dark matter. We consider the possibility that such neutrinos form a thermal bath with a singlet scalar, while not being in thermal…
