  1. 2. Deep-learning boosted hadronic Higgs precise measurements at future e+e− Higgs factories
    Yifan Zhu

    Precise measurements of Higgs decays into quarks and gluons are essential
    for probing the Yukawa couplings of the Higgs boson and testing the flavor structure of the Standard Model. We investigate the process e+e− → ZH at √s = 240 GeV at a future e+e− Higgs factory, taking the CEPC design as a benchmark. Jet flavor is identified using state-of-the-art particle-level deep neural network...

  2. 6. Addressing the Inverse Problem: Spin Identification of Exotic Charged Particles at Future $e^+e^-$ Collider

    Despite its remarkable success, the Standard Model fails to explain phenomena such as neutrino masses, dark matter, and the matter–antimatter asymmetry, motivating a wide range of Beyond the Standard Model (BSM) scenarios. A major challenge in this context is the inverse problem, where different models produce overlapping signatures; hence, identifying the underlying BSM scenario becomes...

  3. 9. [PhD results] Implementation of the Matrix Element Method at NLO for the measurement of the Higgs self coupling
    Matthias Tartarin (TDLI/SJTU)
    12/05/2026, 14:05

    Following the discovery of the Higgs boson, one of the next major achievement at LHC is to observe the production of Higgs pairs and to measure the Higgs tri-linear coupling $\lambda_{3H}$.

    Due to the rarity of di-Higgs production, measuring $\lambda_{3H}$ has proven to be highly challenging.
    The MEM is a statistically optimal multivariate method that maximizes the utilization of both...

  4. 11. Detector R&D of Cold Liquid Scintillator Veto for the PandaX-xT Experiment
    Roni Dey (TDLI,SJTU)
    12/05/2026, 14:20

    The PandaX-xT experiment is a next-generation multi-tonne liquid xenon time projection chamber (TPC) located at the China Jinping Underground Laboratory, designed for ultra-sensitive direct detection of dark matter. As the experiment approaches the neutrino floor, background rejection becomes a critical limiting factor for discovery sensitivity. In particular, cosmogenic neutrons, secondary...

  5. 10. Ionization-only analysis for low energy signals in PandaX-4T
    Minzhen Zhang (SJTU)
    12/05/2026, 14:35

    In the PandaX-4T experiment, the nuclear recoil energy threshold is above 1keV in the conventional search window requiring paired scintillation and ionization signals. This constrains detection sensitivity for low energy signals, such as solar B8 neutrinos and sub-GeV dark matter. By exploiting ionization-only events, we successfully reduce the detection threshold down to 0.33 keV, enabling...

  6. 13. Design and Upgrade of the JUNO DAQ Readout System
    chao chen (TDLI)
    12/05/2026, 14:50

    The Jiangmen Underground Neutrino Observatory (JUNO) aims to determine the neutrino mass ordering and precisely measure neutrino oscillation parameters. Its Data Acquisition (DAQ) system is required to read out, assemble, process online, and store over 40 GB/s of physical data from the front-end electronics. As the first stage of the dataflow software, the readout module's primary tasks...
