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…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
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…
The DAMPE excess and gamma-ray constraints
Konstantin Belotsky, Airat Kamaletdinov, Maxim Laletin +1
The direct measurements of the cosmic electron-positron spectrum around 1 TeV made by DAMPE have induced many theoretical speculations about possible excesses in the data above the…
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…
Can dark matter annihilations explain the AMS-02 positron data?
Maxim Laletin
We show that no dark matter model with the conventional isotropic density distribution can provide a satisfactory explanation of the cosmic positron excess, while being consistent…
A no-go theorem for the dark matter interpretation of the positron anomaly
Maxim Laletin
The overabundance of high-energy cosmic positrons, observed by PAMELA and AMS-02, can be considered as the consequence of dark matter decays or annihilations. We show that recent F…
Fermi-LAT kills dark matter interpretations of AMS-02 data. Or not?
Konstantin Belotsky, Ruslan Budaev, Alexander Kirillov +1
A number of papers attempt to explain the positron anomaly in cosmic rays, observed by PAMELA and AMS-02, in terms of dark matter (DM) decays or annihilations. However, the recent…
High Energy Positrons and Gamma Radiation from Decaying Constituents of a two-component Dark Atom Model
K. Belotsky, M. Khlopov, C. Kouvaris +1
We study a two component dark matter candidate inspired by the Minimal Walking Technicolor model. Dark matter consists of a dominant SIMP-like dark atom component made of bound sta…
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…
Decaying Dark Atom constituents and cosmic positron excess
Konstantin Belotsky, Maxim Khlopov, Chris Kouvaris +1
We present a scenario where dark matter is in the form of dark atoms that can accomodate the experimentally observed excess of positrons in PAMELA and AMS-02 while being compatible…
