Neutrino backgrounds in matter-wave interferometry: implications for dark matter searches and beyond-Standard Model physics

Journal of High Energy Physics
We present a comprehensive theoretical analysis of neutrino-induced decoherence in macroscopic matter-wave interferometry experiments designed to search for dark matter and beyond-Standard Model physics.

Testing nonstandard neutrino properties

Proceedings of 12th Neutrino Oscillation Workshop — PoS(NOW2024)
Neutrinos provide a compelling avenue to explore physics beyond the Standard Model. This proceeding is a brief summary of a plenary talk given at the 12th Neutrino Oscillation Workshop (NOW2024). We present a discussion on various topics on neutrino non-standard properties, such as the origin of neutrino mass, their decay modes, interaction mechanisms,

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Momentum dependent flavor radiative corrections to the coherent elastic neutrino-nucleus scattering for the neutrino charge-radius determination

Journal of High Energy Physics
Despite being neutral particles, neutrinos can have a non-zero charge radius, which represents the only non-null neutrino electromagnetic property in the standard model theory.

Enhanced neutrino polarizability

Journal of High Energy Physics, 2023
We point out that neutrinos can have enhanced couplings to photons, if light (pseudo)scalar mediators are present, resulting in a potentially measurable neutrino polarizability.

Pionic Contribution to Neutrinoless Double Beta Decay

, 2009
It is well known that neutrinoless double decay is going to play a crucial role in settling the neutrino properties, which cannot be extracted from the neutrino oscillation data.

Clarity through the neutrino fog: constraining new forces in dark matter detectors

Journal of High Energy Physics
The PandaX-4T and XENONnT experiments present indications of Coherent Elastic Neutrino Nucleus Scattering (CEνNS) from 8B solar neutrinos at 2.6σ and 2.7σ, respectively.

Bounds on new physics with data of the Dresden-II reactor experiment and COHERENT

Journal of High Energy Physics, 2022
Coherent elastic neutrino-nucleus scattering was first experimentally established five years ago by the COHERENT experiment using neutrinos from the spallation neutron source at Oak Ridge National Laboratory. The first evidence of observation of coherent

Polarimetric Wide‐Angle Radar Detects Competing Signatures of Ice Fabric and Structural Firn Anisotropy

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Ice is mechanically and dielectrically anisotropic. The degree of anisotropy evolves dynamically as ice crystals align during deformation into macroscopic patterns termed ice fabric. Radar polarimetry is an emerging tool to detect such patterns, particularly using nadir‐looking antenna geometries sensitive to horizontal anisotropy.

Constraints on neutrino and dark radiation interactions using cosmological observations

, 2012
Observations of the cosmic microwave background (CMB) and large-scale structure (LSS) provide a unique opportunity to explore the fundamental properties of the constituents that compose the cosmic dark radiation background (CDRB), of which the three ...
