47. LMA-Dark: Large New Physics Effects in Neutrino Oscillations

Dr Peter Denton (Brookhaven National Laboratory)

10/06/2025, 14:00

Talk

In neutrino oscillation physics numerous exact degeneracies exist under the name LMA-Dark. These degeneracies make it impossible to determine the sign of $\Delta m^2_{31}$ known as the atmospheric mass ordering with oscillation experiments alone in the presence of new neutrino interactions. The combination of different measurements including multiple oscillation channels and neutrino...

41. Complementarity between CEνNS and dark matter direct searches experiments for light gauge mediators

Eduardo Peinado

Talk

Searching for dark matter and new light mediators enters a precision era driven by rapid advances in coherent elastic neutrino-nucleus scattering (CEνNS) experiments and direct detection of dark matter. This talk will focus on U(1)′ extensions of the Standard Model. We will explore how CEνNS experiments constrain this sector and how this complements the direct detection results when the light...

55. Precision probes of electroweak and BSM physics with coherent elastic neutrino-nucleus scattering: Insights from CONUS+ and prospects at the upcoming European spallation source

Mr Anirban Majumdar (Indian Institute of Science, Education & Research - Bhopal)

Talk

With the rapid advancement of low-energy neutrino experiments, coherent elastic neutrino-nucleus scattering (CE$\nu$NS) has become a powerful tool for precision studies in both Standard Model (SM) and beyond-the-Standard-Model physics. I will present our recent works based on recent and projected phenomenological studies of CE$\nu$NS at two key facilities: the CONUS+ reactor experiment |1| and...

48. Testing lepton non-unitarity with the next generation of CEvNS reactor experiments

Thomas Rink (Karlsruhe Institute of Technology (KIT))

Talk

In the last years, the long predicted Standard Model reaction channel of coherent elastic neutrino-nucleus scattering (CEvNS) has been confirmed by measurements of (anti-)neutrinos emitted from pion decay at rest sources and nuclear reactors, also with multiple target materials. As we slowly transition with the next generation of experiments from first observations to precision measurements,...
