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 vortex formation and dynamics
TL;DR: In this article , the formation and evolution of vortices in $U(1)$ dark photon dark matter and dark photon clouds that arise through black hole superradiance was studied.

First Indirect Detection Constraints on Axions in the Solar Basin
TL;DR: In this article , the authors place the first limits on the solar basin of axions using recent quiescent solar observations made by the NuSTAR x-ray telescope, and obtain world-leading limits for axions with masses between 5 and 30 keV.
Journal ArticleDOI
Swampland bounds on dark sectors
TL;DR: The Festina Lente bound, the analogue of the Weak-Gravity conjecture in de Sitter, places constraints on the mass and charge of dark particles, which cover regions in parameter space that are currently allowed by observations as discussed by the authors .

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.
