New stellar constraints on dark photons
TLDR
In this article, the stellar production of vector states V within the minimal model of "dark photons" was studied and it was shown that when the Stuckelberg mass of the dark vector becomes smaller than plasma frequency, the emission rate is dominated by the production of the longitudinal modes of V, and scales as κ 2 m V 2, where κ and m V are the mixing angle with the photon and the mass of a dark state.About:

Recent Progress in Search for Dark Sector Signatures
TL;DR: Recently, it has been shown that this spectrum can give rise to unique signatures at colliders when the mass scale in the hidden sector is well below a TeV; as in Hidden Valleys, Stueckelberg extensions, and Unparticle models as mentioned in this paper.

Probing new intra-atomic force with isotope shifts
TL;DR: In this article, the experimental sensitivity to a new force in the test of linearity as well as the linearity violation owing to higher order effects within the Standard Model is discussed. But the sensitivity to new physics is limited by such effects.
Journal ArticleDOI
Galactic Origin of Relativistic Bosons and XENON1T Excess
TL;DR: In this paper, it was shown that this new flux cannot explain the recent XENON1T excess, while assuming that the bosons' couplings to the Standard Model are consistent with all current experimental and observational constraints.

Signatures of dark Higgs boson in light fermionic dark matter scenarios
TL;DR: In this paper, the effect of the dark Higgs boson on both detection prospects and cosmological bounds was studied in the pseudo-Dirac regime and three different scenarios.
Journal ArticleDOI
Gas-rich dwarf galaxies as a new probe of dark matter interactions with ordinary matter
TL;DR: In this article, the authors used observations of gas-rich dwarf galaxies to derive constraints on dark matter scattering with ordinary matter, and they showed that heating/cooling due to dark matter interacting with gas in the Leo T dwarf galaxy not exceed the ultralow radiative cooling rate of the gas.

Two U(1)'s and Epsilon Charge Shifts
TL;DR: If new particles are gauged by a new U(1) then their electromagnetic charges may be shifted by a calculable amount as mentioned in this paper, which is the case in the case of the current article.
Journal ArticleDOI
A theory of dark matter
TL;DR: In this paper, the authors proposed a light boson invoked by XDM to mediate a large inelastic scattering cross section for the DAMA annual modulation signal at low velocities at redshift, which could produce observable effects on the ionization history of the universe.
Journal ArticleDOI
Secluded WIMP Dark Matter
TL;DR: In this article, a generic mechanism via which thermal relic WIMP dark matter may be decoupled from the Standard Model, namely through a combination of WIMPs annihilation to metastable mediators with subsequent delayed decay to Standard Model states, is considered.

The Low-Energy Frontier of Particle Physics
Joerg Jaeckel,Andreas Ringwald +1 more
TL;DR: Most embeddings of the Standard Model into a more unified theory, in particular those based on supergravity or superstrings, predict the existence of a hidden sector of particles that have only very weak interactions with visible-sector Standard Model particles.

WISPy cold dark matter
TL;DR: Very weakly interacting slim particles (WISPs) such as axion-like particles (ALPs) or hidden photons (HPs), may be non-thermally produced via the misalignment mechanism in the early universe and survive as a cold dark matter population until today as mentioned in this paper.
