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:

TL;DR: The EDELWEISS collaboration has performed a search for dark matter (DM) particles interacting with electrons using a 33.4 g Ge cryogenic detector operated underground at the LSM as discussed by the authors.
A force beyond the Standard Model - Status of the quest for hidden photons
TL;DR: In this paper, the search for new gauge forces beyond the standard model was discussed, and an overview for the simplest case of a new U(1), kinetically mixed with the Standard Model photon (hypercharge boson), a so-called hidden photon (also known as dark photon, heavy photon or A').

Solar axion flux from the axion-electron coupling
Javier Redondo,Javier Redondo +1 more
TL;DR: In this paper, the ABC flux is computed from available libraries of monochromatic photon radiative opacities (OP, LEDCOP and OPAS) by exploiting the relations between axion and photon emission cross sections.

Directional Detection of Light Dark Matter with Polar Materials
Sinéad M. Griffin,Sinéad M. Griffin,Simon Knapen,Simon Knapen,Tongyan Lin,Tongyan Lin,Tongyan Lin,Kathryn M. Zurek,Kathryn M. Zurek,Kathryn M. Zurek +9 more
TL;DR: In this paper, the authors considered the direct detection of dark matter (DM) with polar materials, where single production of optical or acoustic phonons gives an excellent reach to the scattering of sub-MeV DM for both scalar and vector mediators using density functional theory.

Searching for Dark Absorption with Direct Detection Experiments
TL;DR: In this article, the absorption by bound electrons of dark matter in the form of axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments are considered.

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.
