Phase Transitions and Gravitational Waves in a Model of Scalar Dark Matter
Nico Benincasa, Andrzej Hryczuk, Kristjan Kannike +1
Theories with more than one scalar field often exhibit phase transitions producing potentially detectable gravitational wave (GW) signal. In this work we study the semi-annihilatin…
Impact of dark matter self-scattering on its relic abundance
Andrzej Hryczuk, Maxim Laletin
Elastic self-scatterings do not change the number of dark matter particles and as such have been neglected in the calculation of its relic abundance. In this work we highlight the…
Dark matter freeze-in from semi-production
Andrzej Hryczuk, Maxim Laletin
We study a novel dark matter production mechanism based on the freeze-in through semi-production, i.e. the inverse semi-annihilation processes. A peculiar feature of this scenario…
Strongly interacting dark matter and the DAMA signal
Maxim Laletin, Jean-René Cudell
We show that models of strongly interacting (SIMP) dark matter built to reproduce the DAMA signal actually cannot account for its time dependence. We discuss the constraints on thi…
Dark matter from CP symmetry of order 4: evolution in the asymmetric regime
Igor P. Ivanov, Maxim Laletin
Multi-Higgs models equipped with global symmetries produce scalar dark matter (DM) candidates stabilized by the unbroken symmetry. It is remarkable that a conserved CP symmetry can…
Multi-Higgs models with CP symmetries of increasingly high order
Igor P. Ivanov, Maxim Laletin
When building CP-symmetric models beyond the Standard Model, one can impose CP-symmetry of higher order. This means that one needs to apply the CP-transformation more than two time…
Dark Atoms and their decaying constituents
Konstantin Belotsky, Maxim Khlopov, Maxim Laletin
The nonbaryonic dark matter of the Universe might consist of new stable charged species, bound by ordinary Coulomb interactions in various forms of heavy neutral "dark atoms". The…
