  1. 63. Neutrino Physics with PandaX
    Ke Han (SJTU)
    03/06/2023, 08:30
    Talk

    Large liquid xenon Time Projection Chambers (TPC) with multi-ton of active mass, such as PandaX-4T, are becoming a powerful tool for neutrino physics. The detector has 350 kg of Xe-136 and can be used to precisely measure the double beta decay spectrum and search for neutrinoless double beta decay (NLDBD). PandaX-4T also has a large amount of another NLDBD candidate isotope, Xe-134 for related...

  2. 65. Vacuum stability limit from cosmological history
    Jin Min Yang (ITP, CAS, Beijing)
    03/06/2023, 08:55
    Talk

    The vacuum stability problem is usually studied assuming that at zero temperature the universe is in the electroweak-breaking vacuum. This may not be the case, however, as seen by checking the evolution history of the early universe in theories beyond the Standard Model. In such models the transition to the electroweak-breaking vacuum may not be possible and/or the universe may have evolved...

  4. 73. Recent progress on neutrino astronomy and the TRIDENT project
    Prof. Donglian Xu (T D Lee Institute)
    03/06/2023, 09:45
    Talk

    With IceCube's discovery of an extragalactic diffuse neutrino flux and first identification of compelling evidence for corresponding sources, TXS0506+056 and NGC 1068, neutrino astronomy is at the tipping point for major breakthroughs. In this talk, I will give a brief overview on the current status of the nascent field of high-energy neutrino astronomy and then discuss the progress on the...

  5. 59. Modular symmetry approach to lepton mixing
    Gui-Jun Ding (University of Science and Technology of China)
    03/06/2023, 13:30
    Talk

    Modular symmetry is a promising approach to address the flavor structure of Standard model. I shall present the recent development on modular symmetry in this talk.

  6. 24. Testing lepton number violation beyond the approach of EFTs
    Gang Li (Sun Yat-sen University)
    03/06/2023, 13:55
    Talk

    In this talk, I will discuss the test of lepton number violation beyond the approach of effective field theories. In the UV completion, one can study LNV interactions with neutrinoless double beta decay, collider searches and low energies precision experiments complementarily.

  7. 18. The Neutrino Magnetic Moment Portal and Supernovae: New Constraints and Multimessenger Opportunities
    Yingying Li (USTC)
    03/06/2023, 14:20
    Talk

    We scrutinize the hypothesis that gauge singlet fermions - sterile neutrinos - interact with Standard Model particles through the transition magnetic moment portal. These interactions lead to
    the production of sterile neutrinos in supernovae followed by their decay into photons and active
    neutrinos which can be detected at γ-ray telescopes and neutrino detectors, respectively. We find
    that...

  8. 83. Status and Physics Prospects of JUNO experiment
    Jie （捷） Cheng （程） (North China Electric Power University)
    03/06/2023, 14:45
    Talk

    The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector currently being built in an underground laboratory in South China. The construction is expected to be completed by the end of 2023. JUNO will feature a remarkable energy resolution of 3% at 1 MeV, a large detector volume, and exceptional background control. With these advantages, JUNO will become a...
