One of the signatures of coherent elastic neutrino-nucleus scattering (CEvNS) is the predicted scaling of the cross section with number of neutrons in the recoiling nucleus squared (N$^2$). The COHERENT collaboration was formed to study CEvNS with a variety of targets to test the physics of CEvNS, including the N$^2$ cross section scaling. As part of COHERENT, a segmented ton-scale NaI[Tl]...

The first observation of coherent elastic neutrino-nucleus scattering (CEvNS) was made by the COHERENT collaboration at the Oak Ridge National Laboratory (ORNL) Spallation Neutron Source (SNS) in August 2017 with a 14.6 kg CsI(Na) detector. One of the physics goals of the COHERENT experiment is to test the N$^2$ dependence of the CEvNS cross section predicted in the Standard Model by...

Neutron stars are cosmic laboratories uniquely poised to answer fundamental questions about the nature of dense neutron-rich matter. However, knowledge of the equation of state of neutron-rich matter is hindered by uncertainties in the neutron distribution of neutron-rich nuclei. Electroweak probes of ground state densities provide a clean and model-independent tool to mitigate these...

Assuming light vector mediators, we discuss the effects of CP violation on the coherent elastic neutrino-nucleus scattering (CEvNS) process in the COHERENT sodium-iodine, liquid argon and germanium detectors. We show that in some regions of the parameter space, the presence of a dip in the event rate spectrum can be used to constraint CP violating effects. In other regions, we find that CP...

We classify new physics signals in coherent elastic neutrino-nucleus scattering (CEvNS) processes induced by B8 solar neutrinos in multi-ton xenon dark matter (DM) detectors. Our analysis focuses on vector and scalar interactions in the effective and light mediator limits after considering the constraints emerging from the recent COHERENT data and neutrino masses. In both cases we identify a...

Coherent elastic neutrino-nucleus scattering (CEvNS) is a neutral-current process in which a neutrino scatters off an entire nucleus, depositing a tiny recoil energy. The process is important in core-collapse supernovae and also presents an opportunity for detection of a burst of core-collapse supernova neutrinos in low-threshold detectors designed for dark matter detection. Here we present an...

Paleo-detectors are a proposed experimental technique in which one would search for traces of recoiling nuclei in ancient minerals. Natural minerals on Earth are as old as $\mathcal{O}(1)\,$Gyr and, in many minerals, the damage tracks left by recoiling nuclei are also preserved for time scales long compared to $1\,$Gyr once created. Thus, even reading out relatively small target samples of...

In experiments aiming on low-interaction energies—exemplified within the low energy neutrinos coherent scatter and quest for low-mass dark matter particles—researchers must understand the underlying noise mechanisms in their detectors.

The first measurement of coherent elastic neutrino-nucleus scattering performed by the COHERENT collaboration in 2017 using a CsI detector has been used to significantly reduce the space of allowed non-standard-neutrino-interaction couplings.
