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:

Cosmological Constraint on Vector Mediator of Neutrino-Electron Interaction in light of XENON1T Excess
TL;DR: In this article, the neutrino-electron interaction mediated by a light vector particle is considered and a light mediator with an effective number of neutrinos Neff in the CMB era is considered.

Probing for an ultralight dark photon from inverse Compton-like scattering
TL;DR: In this paper , the inverse Compton-like scattering process was used to detect the dark photon dark matter through a primary cosmic ray (PCR) scattering process, which can extend the current lower limit of dark photon mass from Jupiter's magnetic fields experiment by about three orders of magnitude.

Lepton number violating electron recoils in a U(1)− model with non-standard interactions
TL;DR: In this article , the neutrino masses and mixings can be generated via Type-I seesaw mechanism after U(1)B−L breaking, and a light mediator emerges and enables non-standard interaction that violates the lepton number.

Particle dispersion in the classical vector dark matter background
TL;DR: In this paper , the authors considered the vector dark matter background with randomly distributed polarizations or a fixed polarization to the single direction and showed that the classical vector field turns out to induce drastic changes in the particle normalization.

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.
