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:

Implications of the XENON1T Excess on the Dark Matter Interpretation
TL;DR: In this article, the authors investigate various scenarios where such dark matter of spin 0 and 1/2 interacts with electrons via an exchange of vector, pseudo-scalar, or scalar mediators.

Stefan Knirck,Stefan Knirck,T. Yamazaki,Yoshiki Okesaku,Shoji Asai,Toshitaka Idehara,Toshiaki Inada +6 more
TL;DR: In this article, a double mirror system composed of a plane and a parabolic mirror is designed to convert HPDMs into photons focused on a receiver, and an upper limit on the photon-HP kinetic mixing χ 10−8 for the mass range of 0.67-0.92 meV was obtained.

Sterile neutrino dark matter catalyzed by a very light dark photon
TL;DR: In this paper, it was shown that if active neutrinos couple to an oscillating condensate of a very light L 1 -L 2 gauge field, resonant neutrino oscillations can occur in the early universe.

Experimental search for solar hidden photons in the eV energy range using kinetic mixing with photons
TL;DR: In this article, a parabolic mirror with a diameter of 500 mm and focal length of 1007 mm installed in a vacuum chamber and a photomultiplier tube at its focal point was used to search for solar hidden photons in the eV energy range.

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.
