21. Neutrinos as a window to MeV-TeV scale new physics

Gang Li (Sun Yat-Sen University)

Abstract: In this talk, I will discuss how neutrinos can act as a window to MeV-TeV scale new physics, including (1) searches for lepton number violation in neutrinoless double beta decay, as well as low-energy precision and high-energy collider experiments; (2) direct and indirect searches for sterile neutrinos; (3) complementary searches for neutrino non-standard interactions, charged lepton...

9. Dark Supercooled Phase Transition as a Key to Unlock the Universe

We build upon the intriguing possibility that the recently reported nano-Hz gravitational wave signal by Pulsar Timing Array (PTA) experiments is sourced by a strong first-order phase transition from a nearly conformal dark sector. The phase transition has to be strongly supercooled to explain the signal amplitude, while the critical temperature has to be in the O(GeV) range, as dictated by...

26. Light neutrinophilic WIMP in the U(1)B−L model

In light of the negative results from WIMP search experiments, attention has shifted toward light thermal DM. Moreover, light DM has the potential to address the core-cusp problem with its large self-scattering rate. However, such models may also predict a high annihilation rate, which could be constrained severely by gamma-ray telescopes. In our study, we explored the possibility of...
