We calculate the solar neutrino and antineutrino flux in the keV energy range. The dominant thermal source processes are photo production (γ e→ e νν̄), bremsstrahlung (e+Ze→ Ze+e+νν̄), plasmon decay (γ→νν̄), and νν̄ emission in free-bound and bound-bound transitions of partially ionized elements heavier than hydrogen and helium. These latter processes dominate in the energy range of a few keV and thus carry information about the solar metallicity. To calculate their rate we use libraries of… 

Solar neutrinos at keV energies: thermal flux

The neutrino flux at Earth is dominated in the keV energy range by the neutrinos produced in the Sun through thermal processes, namely photo production, bremsstrahlung, plasmon decay, and emission in

Constraining neutrino lifetimes and magnetic moments via solar neutrinos in the large xenon detectors

The multi-ton-scale liquid xenon detectors, with an excellent energy resolution of a few keV, will be constructed to probe the dark-matter particles. In this paper, we show that precision

Stellar probes of dark sector-photon interactions

Electromagnetically neutral dark sector particles may directly couple to the photon through higher dimensional effective operators. Considering electric and magnetic dipole moment, anapole moment,

Relic neutrinos at accelerator experiments

We present a new technique for observing low energy neutrinos with the aim of detecting the cosmic neutrino background using ion storage rings. Utilising high energy targets exploits the quadratic

Astrophysical neutrinos: signal and background in searches for fundamental physics

As the experimental boundaries of the energy and intensity frontiers are pushed forwards, astroparticle physics increasingly becomes a key tool to understand the microscopic and macroscopic

Coherent scattering and macroscopic coherence: implications for neutrino, dark matter and axion detection

A bstractWe study the question of whether coherent neutrino scattering can occur on macroscopic scales, leading to a significant increase of the detection cross section. We concentrate on radiative

Neutrino astronomy as a probe of physics beyond the Standard Model: Decay of sub-MeV B−L gauge boson dark matter

The U (1) B – L symmetry, the essential component in the seesaw mechanism and leptogenesis, is naturally equipped with a massive gauge boson. If this gauge boson is the dark matter, the scenario

Probing sub-eV Dark Matter decays with PTOLEMY

When the Dark Matter mass is below the eV-scale, its cosmological occupation number exceeds the ones of photons from the cosmic microwave background as well as of relic neutrinos. If such Dark Matter

Constraints on flavor-diagonal non-standard neutrino interactions from Borexino Phase-II

The Borexino detector measures solar neutrino fluxes via neutrino-electron elastic scattering. Observed spectra are determined by the solar- ν e survival probability P ee ( E ), and the chiral




Photoproduction of a neutrino-- antineutrino pair on an electron is considered. The cross section is calculated and in the nonrelativistic approximation, the power of the photoneutrino flux from a

Solar constraints on hidden photons re-visited

We re-examine solar emission of hidden photons γ' (mass m) caused by kinetic γ–γ' mixing. We calculate the emission rate with thermal field theory methods and with a kinetic equation that includes

Spectra and rates of bremsstrahlung neutrino emission in stars

We calculate the energy-differential rate for neutrino emission from electron-nucleus bremsstrahlung in stellar interiors taking into account the effects of electron screening and ionic correlations.

Gallium solar neutrino experiments: Absorption cross-sections, neutrino spectra, and predicted event rates

Neutrino absorption cross sections for {sup 71}Ga are calculated for all solar neutrino sources with standard energy spectra, and for laboratory sources of {sup 51}Cr and {sup 37}Ar; the calculations

Interactions of keV sterile neutrinos with matter

A sterile neutrino with mass of several keV is a well-motivated dark-matter candidate, and it can also explain the observed velocities of pulsars via anisotropic emission of sterile neutrinos from a

The energy loss rates due to pair, photo-, and plasma neutrino processes are calculated in the framework of the Weinberg-Salam theory for wide ranges of densities and temperatures. Accurate analytic

An analytic approximation to the dispersion equations for photons and plasmons is developed that is correct to order $\ensuremath{\alpha}$ in the classical, degenerate, and relativistic limits for all momenta $k$ and is correct at small $ k$ for all temperatures and electron densities.

Stellar cooling bounds on new light particles: plasma mixing effects

A bstractStrong constraints on the coupling of new light particles to the Standard Model (SM) arise from their production in the hot cores of stars, and the effects of this on stellar cooling. For

Testing keV sterile neutrino dark matter in future direct detection experiments

We determine constraints on sterile neutrino warm dark matter through direct detection experiments, taking XENON100, XENON1T and DARWIN as examples. If keV-scale sterile neutrinos scatter
