Field theory model for dark matter and dark energy in interaction [PDF]

Physical Review D, 2009
We propose a field theory model for dark energy and dark matter in interaction. Comparing the classical solutions of the field equations with the observations of the CMB shift parameter, BAO, lookback time and Gold supernovae sample, we observe a possible interaction between dark sectors with energy decay from dark energy into dark matter. The observed

Singlet-doublet fermionic dark matter in gauge theory of baryons

Journal of High Energy Physics
We are considering a minimal U(1) B extension of the Standard Model (SM) by promoting the baryon number as a local gauge symmetry to accommodate a stable dark matter (DM) candidate. The gauge theory of baryons induces non-trivial triangle gauge anomalies,

Fermionic dark matter in Dynamical Scotogenic Model

Journal of High Energy Physics, 2023
In the Dynamical Scotogenic Model, the global B − L symmetry is supposed to be broken spontaneously resulting in a massless Goldstone boson called majoron, and massive right handed neutrinos which participate in the generation of light neutrino massses ...

Darkonia at colliders

Journal of High Energy Physics
Dark matter may form bound states in a dark sector with an attractive force between two dark matter particles. Searches for dark matter at colliders can differ dramatically from routine searches if bound states, dubbed darkonia, are produced and decay ...

The Migdal effect in semiconductors for dark matter with masses below ∼ 100 MeV

Journal of High Energy Physics, 2023
Dark matter scattering off a nucleus has a small probability of inducing an observable ionization through the inelastic excitation of an electron, called the Migdal effect.

Alternative formation model for antideuterons from dark matter [PDF]

Physical Review D, 2015
Antideuterons are a potential messenger for dark matter annihilation or decay in our own galaxy, with very low backgrounds expected from astrophysical processes. The standard coalescence model of antideuteron formation, while simple to implement, is shown to be under considerable strain by recent data from the LHC.

SIMPly add a dark photon

Journal of High Energy Physics, 2023
Pions of a dark sector gauge group can be strongly interacting massive particle (SIMP) dark matter, produced by the freeze-out of 3 → 2 interactions, with naturally large self-interactions. We study if adding a dark photon to the set-up can do it all: i)

Models of Supersymmetry for Dark Matter [PDF]

EPJ Web of Conferences, 2017
A brief review of supersymmetric models and their candidates for dark matter is carried out. The neutralino is a WIMP candidate in the MSSM where $R$-parity is conserved, but this model has the $ $ problem. There are natural solutions to this problem that necessarily introduce new structure beyond the MSSM, including new candidates for dark matter. In

Search for Milli-Charged particles from the Sun at IceCube

Journal of High Energy Physics, 2022
It is assumed that heavy dark matter particles ϕ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector.
