  1. 38. A DM interpretation of the MB excess and its implications in CEvNS experiments
    Dr Doojin Kim (Texas A & M University (US))
    07/10/2021, 11:30
    Oral

    The MiniBooNE excess has been considered as a potential new physics signal, and various approaches including dark matter interpretations and neutrino-sector physics have been investigated to explain the excess. We revisit the dark matter interpretation, imagining the situation where dark matter emerges from the decays of charged mesons, and discuss a few plausible scenarios that are not in...

  2. 16. Long-lived Scalars at the Neutrino Frontier
    Adrian Raphael Thompson (Texas A & M University)

    Oral

    In light of the MiniBooNE anomaly, which exhibits a puzzling asymmetry in its excess events across the neutrino and antineutrino modes, and across the beam-target and beam-dump modes, I will motivate the searches for long-lived scalar particles and their associated gauge sector. These searches may be undertaken at the neutrino frontier experiments in order to test this solution to the...

  3. 35. Detecting Non-Standard Neutrino Interactions from Solar Neutrinos in Low Threshold Dark Matter detectors
    Thomas Schwemberger (University of Oregon)

    Oral

    As low-threshold dark matter detectors advance in development, they will become sensitive to recoils from solar neutrinos which opens up the possibility to explore neutrino properties. We predict the enhancement of the event rate of solar neutrino scattering due to Non-Standard interactions (NSIs) in low-threshold DM detectors, particularly Skipper-CCDs. We consider five categories of...

  4. 15. Improved study of the ionization efficiency for nuclear recoils in Si and Ge at low energies
    Youssef Sarkis Mobarak (Instituto de Ciencias Nucleares UNAM)

    Oral

    The nuclear recoil ionization efficiency or "quenching factor" (QF) plays a crucial role in low-threshold ionization type detectors aimed at detecting CE$\nu$NS and studying new physics through this channel. We present an improved model based on the integro-differential equation that describes the cascade process initiated by a nuclear recoil, which takes into account a more detailed modeling...

  5. 5. Low-energy CEvNS probes of neutrino electromagnetic properties
    Dimitrios Papoulias (University of Ioannina)
    07/10/2021, 11:59
    Oral

    The effective Majorana neutrino magnetic moment detectable at a scattering experiment involves in reality a combination of fundamental transition magnetic moments (TMMs), CP violating phases and neutrino mixing parameters. Beyond the three neutrino picture, sterile neutrinos with keV-MeV masses and non-zero TMMs can also be probed through low-energy nuclear or electron recoil measurements. We...

  6. 34. Inelastic neutrino-nucleus and dark matter-nucleus scattering
    Wei-Chih Huang (Physics Department, Texas A&M University)
    07/10/2021, 12:08

    We study inelastic neutrino-nucleus and dark matter(DM)-nucleus scattering using argon, cesium, and iodine target nuclei. We use Bigstick, a nuclear shell model code, to obtain the form factors of the nuclei. For the experiment setup (COHERENT and CCM) we estimate event rates for neutrino and dark matter scattering processes. Lastly we estimate cross-section and event rates of the inclusive...
