  1. 49. Detecting Dark Matter Annihilation to Neutrinos

    Neutrino physics

    Considering dark matter annihilation to neutrinos in the Galactic halo, we discuss the prospects for the indirect detection of dark matter using the Hyper-Kamiokande neutrino experiment. We also quantify the extent to which the annihilation of low-mass dark matter to neutrinos could confuse the interpretation of the diffuse supernova neutrino background signal. Finally, we consider a neutrino...

  2. 82. Searching for Dark Matter Annihilation with IceCube and P-ONE

    Neutrino physics

    We present a new search for weakly interacting massive particles utilizing neutrino telescopes. We consider galactic and extra-galactic dark matter and perform an analysis on ten years of public IceCube data. In addition, we compare these results to the potential sensitivity of a new neutrino observatory, P-ONE. Assuming extremely heavy dark matter self-annihilates and produces neutrinos...

  3. 94. Leptogenesis in gauged U(1)_{Lμ-Lτ} model

    Neutrino physics

    A neutral vector boson $Z′$ associated with the gauged $U(1)_{L_\mu−L_\tau}$ can explain the muon g − 2 anomaly without conflicting with experimental searches for the new particle. Under extensions of the Standard Model with the symmetry relating to lepton flavor, neutrino mass generation has been studied through the type-I seesaw mechanism with right-handed neutrinos. In this framework, it is...

  4. 102. Riding the (Type-I) Seesaw: Neutrinos and New Physics

    Neutrino physics

    The Type-I Seesaw model is a simple and elegant way of extending the Standard Model to accommodate neutrino masses. Through quantum effects, massive neutrinos can influence physics in other sectors, leading to various potential observational channels for constraining the parameter space of the Seesaw model. We study a number of these channels.

  5. 83. Seesaw Models and Higgs Physics
    Tobias Felkl (University of New South Wales)

    Neutrino physics

    We study the feasibility to test Seesaw models via precision Higgs measurements at next-generation lepton colliders, and compare the relevant sensitivities to existing constraints from electroweak precision measurements, lepton-flavour non-universality and lepton-flavour violation.
