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:

Revisiting Supernova 1987A constraints on dark photons
TL;DR: In this article, the effects of finite temperature and density on the kinetic mixing parameter, ϵ, in this environment were investigated and it was shown that dark photons with energies above the Wien peak can escape without scattering, contributing more to energy loss than is possible assuming a blackbody spectrum.
Journal ArticleDOI
Solar constraints on hidden photons re-visited
TL;DR: In this paper, the authors re-examine solar emission of hidden photons caused by kinetic mixing and calculate the emission rate with thermal field theory methods and with a kinetic equation that includes γ-γ' ''flavor oscillations'' and γ absorption and emission by the thermal medium.

SENSEI: First Direct-Detection Constraints on Sub-GeV Dark Matter from a Surface Run
M. Crisler,Guillermo Fernandez,Javier Tiffenberg,Tomer Volansky,Tomer Volansky,Juan Estrada,Tien-Tien Yu,Tien-Tien Yu,R. Essig,Miguel Sofo Haro,Miguel Sofo Haro +10 more
TL;DR: The first results from a prototype SENSEI detector are reported, and the implications of these data for several dark matter candidates are discussed, including one model proposed to explain the anomalously large 21-cm signal observed by the EDGES Collaboration.

Cosmology with a very light Lμ − Lτ gauge boson
Miguel Escudero,Miguel Escudero,Dan Hooper,Dan Hooper,Gordan Krnjaic,Mathias Pierre,Mathias Pierre,Mathias Pierre +7 more
TL;DR: In this article, the cosmological implications of an abelian L$μ$ − L$τ$ gauge extension of the Standard Model featuring a light and weakly coupled Z′ were explored in detail.
BookDOI
The Dark Photon
TL;DR: The dark photon is a new gauge boson whose existence has been conjectured as mentioned in this paper, and it is dark because it arises from a symmetry of a hypothetical dark sector comprising particles completely neutral under the Standard Model interactions.

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.
