  3. 40. Majorana versus Dirac, Beyond Neutrinoless Double-Beta Decay
    Andre De Gouvea
    02/11/2024, 11:05

    The nature of neutrinos — Majorana fermions or Dirac fermions — is among the most pressing issues in neutrino physics today. I explore observables capable, in principle, of revealing the nature of neutrinos beyond the well-known searches for neutrinoless double-beta decay. While none are really competitive unless we get very lucky, they help us understand the more “practical" differences...

  4. 8. Tau Tridents at Accelerator Neutrino Facilities
    Diego Lopez Gutierrez (Washington University in St Louis)
    02/11/2024, 11:35

    We present the first detailed study of Standard Model neutrino tridents involving tau leptons at the near detectors of accelerator neutrino facilities. These processes were previously thought to be negligible, even at future facilities like DUNE, based on approximations that underestimated the tau trident cross sections. Our full $2\to 4$ calculation, including both coherent and incoherent...

  5. 10. Looking at the flavor composition of solar neutrinos
    Nityasa Mishra
    02/11/2024, 11:53

    We examine solar neutrinos in dark matter detectors, focusing on flavor-dependent radiative corrections to the coherent elastic neutrino-nucleus scattering (CE$\nu$NS) cross section within a three-flavor framework, incorporating matter effects from the Sun and Earth. Detectors with thresholds $\lesssim 1$ keV and exposures of $\sim 100$ ton-years could probe beyond-tree-level effects and offer...

  6. 34. Probing Scalar Non-Standard Interactions via Flavor Composition of Astrophysical Neutrinos
    Ankur Verma
    02/11/2024, 12:11

    Scalar Non-Standard interaction(SNSI) of neutrinos contribute as modifications to the neutrino mass matrix in the oscillation Hamiltonan and can induce a small active-sterile mass splitting via a Majorana-type interaction due to the matter effect. This framework leads to pseudo-Dirac behavior of neutrinos, introducing rich phenomenology in neutrino oscillations, particularly for high-energy...
