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:

Dark Photon Dark Matter in the Presence of Inhomogeneous Structure
TL;DR: In this article, the authors focus on the implications of heating from dark photon dark matter in the presence of inhomogeneous structure and derive modified constraints on dark photon mass from the Ly-$\alpha$ forest, and show that these experiments will be extremely useful in improving sensitivity to masses near 10-14$ eV.
Supernova Limits on Muonic Dark Forces
TL;DR: In this article , the authors calculate the emission of light dark fermions coupled to leptons via a new massive vector boson, and determine the resulting constraints on the general parameter space.

Probing dark gauge boson with observations from neutron stars
TL;DR: In this paper , the authors investigated the production of light dark gauge bosons by the nucleon bremsstrahlung processes in the core of neutron stars, where the dark vector is assumed to be a $U(1{)-B\ensuremath{-L}$ gauge boson with a mass much below keV.
Journal ArticleDOI
Dark photon dark matter and fast radio bursts
TL;DR: In this paper, the authors investigated the effect of light-dark photons (DP) on the time delay caused by fast radio bursts (FRBs) in the intergalactic medium.

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.
