Boosted dark matter from diffuse supernova neutrinos

  title={Boosted dark matter from diffuse supernova neutrinos},
  author={Anirban Das and Manibrata Sen},
The XENON collaboration recently reported an excess of electron recoil events in the low energy region with a significance of around 3.3σ. An explanation of this excess in terms of thermal dark matter seems challenging. We propose a scenario where dark matter in the Milky Way halo gets boosted as a result of scattering with the diffuse supernova neutrino background. This interaction can accelerate the dark-matter to semi-relativistic velocities, and this flux, in turn, can scatter with the…

Detecting neutrino-boosted axion dark matter in the MeV gap

The elusive nature of Dark Matter (DM) remains a mystery far from being solved. A vast effort is dedicated to search for signatures of feeble DM interactions with Standard Model particles. In this

Probing boosted dark matter composition with high threshold neutrino detectors

: We study the probing prospects of cosmic ray boosted dark matter (DM) in the framework of electron-philic dark photon model. Focusing on the dark matter and dark photon masses around keV ∼ MeV

Blazar constraints on neutrino-dark matter scattering

Neutrino emission in coincidence with gamma rays has been observed from the blazar TXS 0506+056 by the IceCube telescope. Neutrinos from the blazar had to pass through a dense spike of dark matter

Boosting through the Darkness : Bounds on boosted dark matter from direct detection

The recoil threshold of Direct Detection (DD) experiments limits the mass range of Dark Matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM particles.

Cosmic-ray boosted dark matter in Xe-based direct detection experiments

LUX-ZEPLIN (LZ) collaboration has achieved the strongest constraint on weak-scale dark matter (DM)-nucleon spin-independent (SI) scattering cross section in a large region of parameter space. In this

Large-energy single hits at JUNO from atmospheric neutrinos and dark matter

Large liquid scintillator detectors, such as JUNO, present a new opportunity to study neutral current events from the low-energy end of the atmospheric neutrinos, and possible new physics signals due

Revisiting the fermionic dark matter absorption on electron target

We perform a systematic study of the fermionic DM absorption interactions on electron target in the context of effective field theory. The fermionic DM absorption is not just sensitive to sub-MeV DM

No room to hide: implications of cosmic-ray upscattering for GeV-scale dark matter

: The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility of detecting even light dark matter in conventional direct detection experiments or underground

Starburst Nuclei as Light Dark Matter Laboratories

Starburst galaxies are well-motivated astrophysical emitters of high-energy gamma-rays. They are well-known cosmic-ray “reservoirs”, thanks to their large magnetic fields which confine high-energy



Dark Matter Through the Neutrino Portal

We consider a model of dark matter whose most prominent signature is a monochromatic flux of TeV neutrinos from the galactic center. As an example of a general scenario, we consider a specific model

Effective theories for Dark Matter interactions and the neutrino portal paradigm

A bstractIn this article we discuss a general effective-theory description of a multicomponent dark sector with an unspecified non-trivial symmetry and its interactions with the Standard Model
