  5. 7. Asymptotic GUT in extra dimension
    Ye-Ling Zhou (HIAS-UCAS)
    22/11/2025, 10:20

    Asymptotic unification, distinct from the conventional concept of unification, suggests that couplings unify at a fixed point in the deep ultraviolet (UV) limit. Theory with an interacting UV fixed point is normally referred to as asymptotic safety to address the famous UV Landau pole problem. Alternative to a usual grand unified theory (GUT), an asymptotic GUT gradually unifies gauge...

  7. 22. Cosmological phase transitions with low nucleation rates: recent progress and implications
    Yun Jiang
    22/11/2025, 11:10

    We study cosmological phase transitions in the low-nucleation-rate regime, where standard bubble percolation fails. Two distinct mechanisms emerge: (i) a bubble-free transition, in which a higher-energy vacuum within domain walls classically decays into the true vacuum, and (ii) super-Hubble separated bubbles, leading to ultra-supercooled or reheated transitions. These scenarios reveal...

  8. 20. Cosmological signatures of neutrino seesaw mechanism
    Chengcheng Han (Sun Yat-sen university)
    22/11/2025, 11:35

    The tiny neutrino masses are most naturally explained by seesaw mechanism through singlet right-handed neutrinos, which can further explain the matter-antimatter asymmetry in the Universe. In this work, we propose a new approach to study cosmological signatures of neutrino seesaw through the interaction between inflaton and right-handed neutrinos, which respects the shift symmetry. In our...

  11. 21. Probing lepton flavor mixing at colliders and in low-energy experiments
    Gang Li (Sun Yat-Sen University)
    22/11/2025, 14:50

    I will talk about several proposals, which aim to uncover lepton flavor mixing in the right-handed sector through processes at various colliders and in low-energy experiments.

  12. 5. Sterile Neutrino Oscillations with a Crossing-width Term
    Yi-Lei Tang (中山大学)
    22/11/2025, 15:15

    We developed an algorithm to compute the oscillation and decay of a sterile neutrino generated at a collider in the case that a crossing-width term exist. We also looked into the hidden structure of the S-matrix to extract the oscillating informations.

  16. 1. Constraining long-lived particles from Higgs boson decays at the LHC with displaced vertices and jets
    Zeren Simon (泽人) Wang (王) (Hefei University of Technology)
    22/11/2025, 17:25

    Long-lived particles (LLPs) originating from decays of Standard-Model-like or beyond-the-Standard-Model Higgs bosons are often featured with signatures of displaced vertices (DVs) and jets at colliders. In this work, we show that a recent ATLAS search for DVs plus jets, with its recast implementation, can efficiently place bounds on such hadronically or semileptonically decaying LLPs. In...

  19. 18. Measuring Phase Transition Gravitational Waves and Higgs Self-couplings
    Huaike Guo (University of Chinese Academy of Sciences)
    23/11/2025, 09:00

    I will discuss how to measure the gravitational wave spectrum from cosmological first order phase transitions, in particular the Electroweak phase transitions, and how to then predict observables which are important but difficult to measure by other experiments, like the Higgs self-couplings.

  20. 8. Relaxing BBN constraints on Heavy Neutral Leptons with Axion-like Particles
    Chayan Majumdar (IMP, CAS)
    23/11/2025, 09:25

    Heavy neutral leptons (HNLs) are constrained by requirements of Big Bang Nucleosynthesis (BBN) as their decays significantly impact the formation of the primordial elements. We propose here a model where the primary decay channel for the HNLs is to an axion-like particle (ALP) and a neutrino. Consequently, HNLs can decay earlier and evade the BBN bound for lower masses, provided the ALPs...

  22. 4. Leptophilic axionlike particles at forward detectors
    Dr Chih-Ting Lu (Nanjing Normal University)
    23/11/2025, 10:45

    Leptophilic axion-like particles (ALPs) exhibit rich phenomenology, focusing exclusively on interactions between an ALP and Standard Model (SM) leptons. Through integration by parts, it is shown that both the three-point interaction, $a\bar\ell\ell$, and the four-point interaction, $a\ell^-\nu W^+$, play significant roles, making the flavor portal particularly compelling. For ALPs with masses...

  23. 3. Loop-level lepton flavor violation in the left-right symmetric model
    Peiwen Wu (Southeast University)
    23/11/2025, 11:10

    We consider the lepton flavor violation (LFV) processes generated at loop-level in the left-right symmetric model (LRSM). We pay special attention to the parameter space in which a light exotic CP-even scalar is produced in beam dump experiments or astrophysical processes. When the light scalar behaves as a long-lived particle, various current searches and prospects for future facilities can...

  24. 19. CP Violation Beyond SM: Dark Photon and Goldstone boson Frameworks
    Jin Sun (韩国基础研究院)
    23/11/2025, 11:35

    This talk explores CP violation (CPV) in theories beyond the Standard Model (BSM). It addresses the long-standing puzzle that known CPV sources within the SM are insufficient to explain the observed matter-antimatter asymmetry of the universe, necessitating the identification of new CPV mechanisms. We present a systematic study of CPV mediated by two distinct BSM carriers: the dark photon and...
