36. CEνNS phenomenology with first data at direct detection experiments

Valentina De Romeri (IFIC CSIC/UV (Valencia, Spain))

09/06/2025, 14:00

Talk

In this talk I will discuss some implications of the first indication of nuclear recoils from solar neutrinos on a xenon target at direct detection experiments. By analyzing data from the XENONnT and PandaX-4T experiments, I will present the first constraints on new interactions and neutrino electromagnetic properties from the first CEνNS data using solar 8B neutrinos.

20. The Standard Model tested with neutrinos

Talk

The Standard Model (SM) has consistently provided a robust description of particle interactions, yet intriguing anomalies, particularly within the neutrino sector, suggest potential areas for further exploration. In this talk, we present a comprehensive global fit of coherent elastic neutrino-nucleus scattering (CEνNS) data from COHERENT (CsI, Ar), CONUS+, TEXONO, and neutrino-electron...

25. Unveiling Electroweak Physics in The Germanium CEνNS Era

Mattia Atzori Corona (Sapienza Universita e INFN, Roma I (IT))

Talk

Coherent Elastic Neutrino-Nucleus Scattering (CEνNS) is a powerful tool for probing both Standard Model (SM) and beyond-SM (BSM) physics. The remarkable CEνNS observations from the CONUS+ collaboration at nuclear reactors using a germanium target explore the fully coherent regime at unprecedentedly low energies, where nuclear structure uncertainties play a marginal role.

51. Oscillation portals to new physics with CEvNS and nu-e scattering

Talk

In this talk I will present some novel ideas to constrain new forces coupled to a secluded sector of particles. To access these sectors, neutrinos must first oscillate via (ultra-)long-baseline oscillations to the dark fermions. Then, via a dark photon or similar mediators, these dark fermions induce CEvNS or nu-e scattering events in underground detectors. These scenarios also typically...
