35. Phenomenology of CEvNS from reactor antineutrinos

Gonzalo Sanchez Garcia (Instituto de Física Corpuscular CSIC/UV (Valencia, Spain))

11/06/2025, 11:15

Talk

The detection of CEvNS from reactor sources represents a unique opportunity to test beyond the Standard Model physics in the neutrino sector. In this talk, we present the phenomenological implications of the first CONUS+ observation of CEvNS for different new physics scenarios, including non-standard interactions, electromagnetic properties of neutrinos and light mediators. The results...

42. Neutrino fog and Dark Matter Direct Detection Experiments: A BSM point of view

Talk

As direct detection experiments approach sensitivities where neutrinos become an irreducible background due to their interactions via coherent elastic neutrino-nucleus scattering (CEvNS), they pose a fundamental limitation in the search for Dark Matter. Given that CEvNS has only recently been observed, there remains significant room for new physics beyond the Standard Model (BSM) to alter the...

10. Ionization Efficiency for pure crystals at low energies

Talk

Understanding ionization efficiency at energies below 1 keV, both in pure crystals and in noble liquid detectors, provides an essential analytical tool for accurate measurements of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) and the processes involved in the search for dark matter. This presentation will address theoretical concepts related to the Lindhard integral equation and the...

22. Detection of Elastic Coherent Neutrino Scattering, Qubit Decoherence, and Energy Accumulation-Release Processes in Materials

Talk

The detection of nuclear recoils caused by elastic coherent scattering of solar and reactor neutrinos is of significant scientific and practical importance, representing a key milestone in the direct search for dark matter particles. While modern detectors are sensitive to registering these small energy depositions, a challenge lies in discriminating particle interactions from energy...

28. Neutrino magnetic dipole portal with low energy neutrino nucleus scattering data

Prof. Yufeng Li (Institute of High Energy Physics, Beijing)

Talk

Sterile neutrinos that couple to the Standard Model via the neutrino magnetic dipole portals have been extensively studied at various experiments. In this work, we scrutinize these interactions for sterile neutrinos in the mass range of 0.1--50 MeV through the nuclear and electron recoils at various neutrino scattering experiments. For the e-flavor specific dipole portal, we demonstrate that...
