    Talk
  2. 108. Status and prospects of CDEX
    Mr Shukui Liu (Sichuan University)

    Talk

    The China Dark Matter Experiment (CDEX) pursues direct searches of light dark matter particles and neutrinoless double beta decay at the China Jinping Underground Laboratory (CJPL), which is the deepest operating laboratory for astroparticle research.
    The CDEX employs germanium semi-conductor detector which has low energy threshold and excellent energy resolution. We report the latest novel...

  3. 62. dark matter searches with PandaX experiment
    Ning Zhou (Shanghai Jiao Tong University)
    02/06/2023, 09:20
    Talk

    PandaX experiment uses xenon as target to detect weak and rare physics signals, including dark matter and neutrinos. We are running a new generation detector with 4-ton xenon in the sensitive volume, PandaX-4T. The commissioning run data has pushed the constraints on WIMP-nucleon scattering cross section to a new level. In this talk, I will give an overview of PandaX-4T latest results on dark...

  4. 29. Probing Cosmic Beam-dump DM in Direct Detections
    Lei Wu (Nanjing Normal Univeristy)
    02/06/2023, 13:30
    Talk

    In this talk, I will talk about the production of sub-GeV DM from the cosmic ray collision with the atmosphere and the prospects in direct detection. I will highlight the importance of quasi-elastic scattering in the earth-stopping effect.

  5. 6. Dark matter searches with the CMB
    Dr Yu Gao (IHEP)
    02/06/2023, 13:55
    Talk

    Dark matter candidates like the WIMPs and primordial black holes are involved in long-time scale energy emission processes, such as annihilation, decay, black hole evaporation and accretion. Such energy injection during the dark age of the Universe modifies the cosmic ionization and temperature evolution, which lead to observeable impacts on the anistropy spectrum of the cosmic microwave...

  6. 32. Asymmetric dark matter with a spontaneously broken U(1)': self-interaction and gravitational waves
    Mengchao Zhang (Jinan University)
    02/06/2023, 14:20
    Talk

    Motivated by the collisionless cold dark matter small scale structure problem, we propose an asymmetric dark matter model where dark matter particle interact with each other via a massive dark gauge boson. This model easily avoid the strong limits from cosmic microwave background (CMB) observation, and have a large parameter space to be consistent with small scale structure data. We focus on a...

  7. 107. Probing Mirror Twin Higgs with Present and Future Weak Lensing Surveys
    Yue-Lin Sming Tsai (Purple Mountain Observatory)
    02/06/2023, 14:45
    Talk

    We explore the potential of precision cosmological data to study non-minimal dark sectors by updating the cosmological constraint on the mirror twin Higgs model (MTH). The MTH model addresses the Higgs little hierarchy problem by introducing dark sector particles. In the early Universe, the mirror baryon and mirror radiation behave as dark matter and dark radiation, and their presence modifies...
