Model-independent analysis of the DAMPE excess

Journal of High Energy Physics, 2018
The Dark Matter Particle Explorer (DAMPE) recently released measurements of the electron spectrum with a hint of a narrow peak at about 1.4 TeV. We investigate dark matter (DM) models that could produce such a signal by annihilation in a nearby subhalo ...

Gravitational production of vector dark matter

Journal of High Energy Physics, 2020
A model of vector dark matter that communicates with the Standard Model only through gravitational interactions has been investigated. It has been shown in detail how does the canonical quantization of the vector field in varying FLRW geometry implies a ...

Electroweak phase transition and gravitational waves in a two-component dark matter model

Journal of High Energy Physics, 2022
We investigate an extension of the Standard Model (SM) with two candidates for dark matter (DM). One of them is a real scalar field and the other is an Abelian gauge field.

The European Physical Journal Plus
The general real singlet extension of the Standard Model (SM), the RxSM, is one of the simplest theories Beyond-the-Standard Model (BSM) that can accommodate a strong first-order electroweak phase transition (SFOEWPT). We investigate the possible thermal

Baryonic Higgs and dark matter

Journal of High Energy Physics, 2021
We discuss the correlation between dark matter and Higgs decays in gauge theories where the dark matter is predicted from anomaly cancellation. In these theories, the Higgs responsible for the breaking of the gauge symmetry generates the mass for the ...

Cosmological constraint on vector mediator of neutrino-electron interaction in light of XENON1T excess

Journal of High Energy Physics, 2020
Recently, the XENON1T collaboration reported an excess in the electron recoil energy spectrum. One of the simplest new physics interpretation is a new neutrino-electron interaction mediated by a light vector particle.

When freeze-out occurs due to a non-Boltzmann suppression: a study of degenerate dark sector

Journal of High Energy Physics, 2021
Exponential suppression or commonly known as the Boltzmann suppression in the number density of dark matter is the key ingredient for creating chemical imbalance prior to the usual thermal freeze-out.

Euclid preparation. LXXI. Simulations and nonlinearities beyond LambdaCDM. 3. Constraints on f(R) models from the photometric primary probes [PDF]

Astronomy & Astrophysics
We study the constraint on f(R) gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint on the theoretical modelling of the nonlinear matter power spectrum.

From Particle Physics to Gravitational Waves: The Electroweak Phase Transition as a Cosmic Bridge to New Physics

Advances in Engineering Technology Research
The observed baryon asymmetry of the Universe is a fundamental puzzle that cannot be explained by the Standard Model (SM) of particle physics. An effective first-order electroweak phase transition (FOEWPT) is an essential component of electroweak ...
