71. Searches for Nonstandard Neutrino Oscillations at Nuclear Reactors

Jeffrey Berryman (University of California, Berkeley)

11/02/2022, 11:45

Nuclear reactors have been workhorses for neutrino physics since its inception, and have been critical in establishing neutrino oscillations. While the three-oscillating-neutrino paradigm has been remarkably successful, long-standing anomalies at LSND, MiniBooNE, gallium experiments and reactor experiments may be pointing to the existence of new physics that can affect this phenomenon. In this...

67. BSM Physics Potential of the PROSPECT-II Experiment

Pranava Teja Surukuchi

The Precision Reactor Oscillation and SPECTrum (PROSPECT) experiment is a short baseline reactor neutrino experiment that produced one of the world-leading limits on eV-scale sterile neutrinos and performed a precision measurement of the reactor antineutrino spectrum from the High Flux Isotope Reactor--a highly enriched uranium reactor--located at Oak Ridge National Laboratory. PROSPECT also...

73. Hidden Sector Searches With Low-Threshold Reactor-Based Neutrino Experiments

Jingke Xu (Lawrence Livermore National Laboratory)

The recent observation of coherent neutrino-nucleus elastic scattering, or CEvNS for short, provides a novel window to probe standard and beyond standard physics in the neutrino sector. A key feature of nuclear interactions is when the momentum transferred to the nucleus is relatively small, near or below the MeV scale, so that the neutrino can coherently scatter off the whole nucleus instead...

61. Searching for Neutrinoless Double Beta Decay with Xenon-doped Liquid Argon TPCs

Andrew Mastbaum (Rutgers University), Joseph Zennamo, Fernanda Psihas (Fermi National Accelerator Laboratory)

11/02/2022, 12:30

The physics programs of LArTPCs primarily focus on signals in the GeV energy range. In recent years, the potential for LArTPCs as a low-energy experiment has been fruitfully explored, specifically regarding its sensitivity to signals as low as 5-10 MeV such as those associated with supernova burst and solar neutrinos in DUNE. In this presentation, we will discuss the requirements and...

60. Study of invisible neutrino decay at ESSnuSB

Dr Monojit Ghosh (University of Hyderabad, Hyderabad, India)

11/02/2022, 12:45

In this presentation I will discuss the phenomena of invisible neutrino decay in which a heavy active neutrino state decays into a light sterile neutrino state and present a comparative analysis of two baseline options, 540 km and 360 km, for the ESSnuSB experimental setup. In particular, I will discuss the capability of this experiment to: (i) put a bound on the decay parameter, (ii)...

69. Improving CP Sensitivity with Muon Decay at Rest

Pedro Pasquini

11/02/2022, 13:00

At long-baseline experiments, the genuine CP effect from the PMNS mixing matrix can be faked by the ubiquitous matter effect. The reduction of the experimental sensitivity to $\delta_D$ drops by 20% due to matter density uncertainties. In this work we present an experimental configuration that combines the DUNE experiment with a muon decay-at-rest ($\mu$DAR) source. The $\mu$DAR source...
