“…There are various types of radiative interactions giving contributions to the stellar cooling process [158]. While some of the astrophysical observations are subject to large uncertainties in both the measurement and the model [159], a large region in the parameter space (G R , m N ) preserving DM constraints (2.12)-(2.14) is offered to be consistent with both the astrophysical observation and XENON1T new results.…”

The XENON1T collaboration recently reported the excess of events from recoil electrons, possibly giving an insight into new area beyond the Standard Model (SM) of particle physics. We try to explain this excess by considering effective interactions between the sterile neutrinos and the SM particles. In this paper, we present an effective model based on one-particle-irreducible interaction vertices at low energies that are induced from the SM gauge symmetric four-fermion operators at high energies. The effective interaction strength is constrained by the SM precision measurements, astrophysical and cosmological observations. We introduce a novel effective electromagnetic interaction between sterile neutrinos and SM neutrinos, which can successfully explain the XENON1T event rate through inelastic scattering of the sterile neutrino dark matter from Xenon electrons. We find that sterile neutrinos with masses around 90 keV and specific effective coupling can fit well with the XENON1T data where the best fit points preserving DM constraints and possibly describe the anomalies in other experiments.

“…We show only the strongest existing constraints on the relevant parameter space. In principle, astrophysical bounds on our scenario could also apply, however, these are typically weaker than those discussed here and are less robust (see [56][57][58] for recent discussions). For the sake of clarity, these constraints are presented for the standard galactic UDM halo only.…”

A possible implication of an ultralight dark matter (UDM) field interacting wibeginth the Standard Model (SM) degrees of freedom is oscillations of fundamental constants. Here, we establish direct experimental bounds on the coupling of an oscillating UDM field to the up, down, and strange quarks and to the gluons, for oscillation frequencies between 10 Hz and 10 8 Hz. We employ spectroscopic experiments that take advantage of the dependence of molecular transition frequencies on the nuclear masses. Our results apply to previously unexplored frequency bands, and improve on existing bounds at frequencies > 5 MHz. We identify a sector of UDM -SM coupling space where the bounds from Equivalence Principle tests may be challenged by next-generation experiments of the present kind.

“…This goes beyond that excluded by previous direct laboratory experiments searching for ALP-mediated exotic pseudo-scalar interactions between protons that have shown that f int ≳ 300 GeV over the ALP mass range probed by GNOME 39 . Although astrophysical observations suggest that f int ≳ 2 × 10 8 GeV, there are a variety of scenarios in which such astrophysical constraints can be evaded 40 , 41 . The parameter space for f int and m a explored in this search is well outside the typical predictions for axions in quantum chromodynamics 42 , 43 .…”

Search for topological defect dark matter with a global network of optical magnetometers

Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that could concentrate the dark matter density into many distinct, compact spatial regions that are small compared with the Galaxy but much larger than the Earth. Here we report the results of the search for transient signals from the domain walls of axion-like particles by using the global network of optical magnetometers for exotic (GNOME) physics searches. We search the data, consisting of correlated measurements from optical atomic magnetometers located in laboratories all over the world, for patterns of signals propagating through the network consistent with domain walls. The analysis of these data from a continuous month-long operation of GNOME finds no statistically significant signals, thus placing experimental constraints on such dark matter scenarios.
