In recent years, coherent elastic neutrino nucleus scattering (CEvNS) has proven to be a useful tool for probing low-energy electroweak physics [1]. In this talk I will present the new constraints extracted on the weak mixing angle and nuclear physics [2] in the light of the latest CEvNS data reported by the COHERENT collaboration [3]. I will finally discuss briefly the implications of the new...
Using an effective field theory approach,we study coherent neutrino scattering on nuclei, in the setup pertinent to the COHERENT experiment. We include non-standard effects both in neutrino production and detection, with an arbitrary flavor structure, with all leading Wilson coefficients simultaneously present, and without assuming factorization in flux times cross section. A concise...
In this talk, I discuss the possibility to set limits on neutrino electromagnetic properties using the data of the COHERENT experiment and the Dresden-II reactor. I discuss neutrino magnetic moments, charge radii and millicharges. In order to obtain the bounds, the contribution of elastic neutrino-electron scattering, which can become strongly effected for some of the parameters that are...
In neutrino oscillation physics numerous exact degeneracies exist under the name LMA-Dark which make it impossible to determine the sign of the atmospheric mass splitting in oscillation experiments.
I will discuss how new data from the Dresden-II experiment completely removes the degeneracies in the $\nu_e$ sector for mediators down to the MeV scale at which point constraints from the early...
Very recently, the Dresden-II Collaboration has reported a suggestive piece of evidence pointing to the first ever observation of CE$\nu$NS using reactor $\overline{\nu}_e$ [1]. The new Dresden-II data have prompted phenomenological analyses that resulted in complementary constraints on various parameters within and beyond the Standard Model (SM). In this talk I will briefly discuss our...
The observation of coherent elastic neutrino-nucleus scattering (CEνNS) performed at the COHERENT experiment with a cesium iodide detector and with a liquid argon detector, represents an innovative and powerful tool to study many physical phenomena.
In particular, CEνNS represents a sensitive probe for interactions that are not included in the Standard Model, as for instance interactions...
Neutrino-nucleus interactions play a role in (anti)neutrino scatterings off nuclei, nuclear beta and double beta decays, nuclear electron and muon captures, etc. These processes involve nucleons, protons and neutrons, and their (collective) conglomerates, the nuclei. Neutrino-nucleus interactions are driven by the weak neutral and charged currents, consisting of a vector and an axial-vector...
Neutrino non-standard interactions (NSI) have been extensively explored in the context of dedicated neutrino experiments. However, the next generation of direct detection experiments is on course to observe a significant number of solar neutrino events, and the sensitivities of these experiments within the NSI landscape are yet to be determined. Due to their sensitivity to neutrino-nucleus and...
After the first CE$\nu$NS detections, further experiments with different technologies have been established and the question arises how to further exploit this signal for a wide variety of investigations in the future. In this context, nuclear reactors with their intense emission of low-energy antineutrinos in combination with high-purity germanium detectors have already shown their potential...
The process of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) has shown to be sensitive to constrain new physics parametrized by Non-Standard Interactions (NSI). In this talk, we review the current bounds on NSI parameters when combining the recent results from the COHERENT collaboration using CsI and LAr detectors [1]. In addition, we present the expected sensitivities that can be...
