“…New dark-matter-neutrino interactions can leave important imprint in various aspects of cosmology, such as the cosmic microwave background (CMB) [17][18][19], and the structure formation from large to small scales [20][21][22][23][24][25][26][27]. Experimentally, neutrinos from dark matter annihilation at the center of the galaxy or the sun have long been proposed and searched for using neutrino telescopes [28][29][30][31][32][33][34][35][36][37][38][39]. The attenuation effect in the flux of high energy neutrinos from distant astrophysical sources due to the travel through the cosmic dark matter background has also been explored in Refs.…”

We introduce the mono-neutrino signal at neutrino detectors as a smoking gun of sub-GeV scale dark matter candidates that mainly interact with standard model neutrinos. In a mono-neutrino process, invisible particles, either dark matter themselves or the mediator particle, are radiated off a neutrino when it undergoes the charged-current weak interaction. The associated signals include a missing transverse momentum with respect to the incoming neutrino beam direction and the production of wrong-sign charged leptons. We demonstrate the potential leading role of the future DUNE experiment, using its proposed liquid and gas argon near detectors, in probing these new signals and the thermal origins of neutrinophilic dark matter.

“…Possible constraints from the cosmic neutrinos and gamma ray on IVDM have been discussed in Refs. [32][33][34]. Recently the BESS-Polar II experiment has measured the antiproton flux in the energy range from 0.2 GeV to 3.5 GeV [35] which have higher precision compared with that from PAMELA [36] at low energies.…”

Implications of the latest XENON100 and cosmic ray antiproton data for isospin-violating dark matter

In the scenario of isospin violating dark matter (IVDM), the dark matter (DM) spin-independent couplings to protons and to neutrons are allowed to be different, which has been considered to relax the tensions between the results of DAMA, CoGeNT and XENON experiments. We explore the allowed values of DM-nucleon couplings favored and excluded by the current experiments under the assumption of IVDM. We find that the recently updated XENON100 result excludes the main part of the overlapping signal region between DAMA and CoGeNT. We also show that the possible tensions between some experiments such as that between DAMA and SIMPLE are unlikely to be affected by isospin violating interactions. In an effective operator approach, we investigate conservative upper bounds on the DM-quark couplings required by the IVDM scenario from the cosmic ray antiproton fluxes measured recently by BESS-Polar II and PAMELA, and that from the relic density. The results show that the relatively large couplings favored by DAMA and CoGeNT are tightly constrained, if the operators contribute to velocity-independent annihilation cross sections. For thermal relic DM, the upper bounds from the relic density can also be stringent. *

“…The SK experiment has taken data for 1679.6 days with an effective area of 10 3 m 2 , and set an upper limit on the number of high energy neutrinos above a GeV beyond the atmospheric neutrino background, which is around ∼ 10 [35,36]. We will consider the GDM mass above a few GeV scale.…”

We investigate the possibility that the dark matter candidate is from a pure non-abelian gauge theory of the hidden sector, motivated in large part by its elegance and simplicity. The dark matter is the lightest bound state made of the confined gauge fields, the hidden glueball. We point out this simple setup is capable of providing rich and novel phenomena in the dark sector, especially in the parameter space of large N . They include self-interacting and warm dark matter scenarios, Bose-Einstein condensation leading to massive dark stars possibly millions of times heavier than our sun giving rise to gravitational lensing effects, and indirect detections through higher dimensional operators as well as interesting collider signatures.
