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:

Phenomenology of the Massive Dark Photon
TL;DR: In this article, the strength of this interaction is modulated by the mixing parameter, and the parameter space for the experimental searches is given by the mass of the dark photon and the mixing parameters.

Secluded dark sector and muon (g-2) in the light of fast expanding Universe
TL;DR: In this paper , the authors considered the presence of a new species ϕ whose energy density redshifts as a -4+n where n > 0 and a is the scale factor.
Journal ArticleDOI
Ghost Imaging of Dark Particles
TL;DR: In this article, the authors proposed a new way to use optical tools from quantum imaging and quantum communication to search for physics beyond the standard model, where a new dark sector particle replaces the idler.

Hidden sectors and a multi-temperature universe
TL;DR: In this article, the authors discuss the possibility that the visible sector and the hidden sectors in general live in different heat baths, and demonstrate a realization of this possibility in a universe with two hidden sectors.

Wideband Direct Detection Constraints on Hidden Photon Dark Matter with the QUALIPHIDE Experiment
TL;DR: In this paper , the authors reported direction detection constraints on the presence of hidden photon dark matter with masses between 20-30 μeV c^{-2], using a cryogenic emitter-receiver-amplifier spectroscopy setup designed as the first iteration of QUALIPHIDE (quantum limited photons in the dark experiment).

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.
Journal ArticleDOI
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.
