Experiments at the Large Hadron Collider produce some of the most complex datasets in science. A central challenge in high-energy physics is to extract rare signals, reconstruct invisible particles such as neutrinos, and search for subtle deviations from the Standard Model with maximal sensitivity. These are fundamentally physics problems, but their scale and complexity call for new...

Precision measurements of Higgs, W, and Z bosons at future lepton colliders demand jet energy reconstruction with unprecedented accuracy. The particle flow approach has proven to be an effective method for achieving the required jet energy resolution. We present CyberPFA, a particle flow algorithm specifically optimized for the crystal bar electromagnetic calorimeter (ECAL) in the CEPC...

We propose a novel method for reconstructing Laurent expansion of rational functions using p-adic numbers. By evaluating the rational functions in p-adic fields rather than finite fields, it is possible to probe the expansion coefficients simultaneously, enabling their reconstruction from a single set of evaluations. Compared with the reconstruction of the full expression, constructing the...

The Gamma-Ray and AntiMatter Survey (GRAMS) is a next-generation experiment using a Liquid Argon Time Projection Chamber (LArTPC) detector to detect gamma rays and antiparticles. Gamma-ray surveys are important for understanding multi-messenger and time-domain astronomy, enabling exploration of the universe's most potent events, such as supernovae and neutron star mergers etc. Despite the...

The indirect detection of axions can enable us to probe axion parameters with various astrophysical and cosmological observations. In this talk, I will discuss new dynamics and phenomena that are unique to axions, such as the formation of axion miniclusters and axion stars. Then I will introduce some new ideas on testing these new phenomena, which can enhance the sensitivity and motivate more...

QCD axion can explain the strong CP problem and dark matter (DM) simultaneously. If the Peccei-Quinn (PQ) symmetry is spontaneously broken after inflation, string-wall network would dominate the energy density in the Universe. In this talk, we consider a mixing coupling of the PQ scalar with a light scalar field which induces an extra axion potential. When the PQ scalar is mixed nonlinearly,...

The search for Weakly Interacting Massive Particles (WIMPs) still holds many mysteries. Beyond the well-studied spin-independent (SI) interaction, the spin-dependent (SD) coupling is crucial for determining whether WIMPs can interact with the spin of nucleons.
Typically, SD interactions are searched for in the elastic-scattering region (0-25 keV). However, it is challenging to distinguish...

The Deep Underground Neutrino Experiment (DUNE) is a next-generation experiment designed to achieve unprecedented precision in the study of neutrino flavour oscillations. To minimize systematic uncertainties associated with neutrino flux predictions and interaction cross-sections, DUNE will utilize a sophisticated near detector (ND) complex. Among its three ND subsystems, the System for...

Fragmentation functions (FFs) are crucial non-perturbative components in quantum chromodynamics (QCD), playing a vital role in predictions and understanding of the hadronization process. In this paper, we present the FFs for K_S^0, \eta, \pi^0 mesons, and \Lambda baryons in the context of global QCD analysis. The data included in the fit are from single inclusive e^+ e^- annihilation (SIA),...

Deep learning is reshaping how we study jets at the Large Hadron Collider (LHC). By learning from the complex patterns of hadronic activity, modern jet-tagging models are opening new possibilities for discovery. In this talk, I will present our recent advances in building large-scale pretrained models for jets, designed to be broadly applicable across the LHC physics program. Such models can...

Strange metals, found in high-temperature superconductors and other strongly correlated systems, display unconventional transport such as robust linear-in-temperature resistivity that defies Fermi liquid theory. My research explores a disorder-driven approach inspired by the Sachdev–Ye–Kitaev (SYK) model, showing that linear resistivity persists under scalar and vector random couplings, even...

The Standard Model Higgs field can play an essential role in the very early Universe to realize the cosmic inflation, providing proper initial conditions for the hot big bang theory. However, the vanilla Higgs inflation model suffers from the unitarity problem when the Higgs field decays into gauge bosons after inflation, as the momentum of the produced gauge bosons can be higher than the UV...

During inflation, the inflaton can undergo significant changes. If the inflaton field is coupled to other fields, phase transitions may occur in the coupled fields as the inflaton evolves. The curvature perturbations and gravitational waves generated by the phase transition may be detectable and could provide insights about inflation. We explore the possible curvature perturbation and the...

We examine first-order phase transitions within a hidden $U(1)_X$ sector as potential sources of stochastic gravitational wave backgrounds, with particular emphasis on supercooling and gauge invariance considerations. We establish that supercooled phase transitions provide a viable mechanism for explaining observed pulsar timing array signals and demonstrate that the distinct thermal...

Topological field solutions – such as sphaleron, monopole, and cosmic strings – can have important implications on the unsolved questions of our universe, notably the origin of baryon asymmetry and the nature of dark matter. Many baryogenesis mechanisms (for example, electroweak baryogenesis and leptogenesis) depend on sphaleron transition; consequently, a theoretical rubost and consistent...

Long-lived particles (LLPs) have a clear signature of physics beyond the Standard Model (BSM), characterized by displaced vertex or decay lengths corresponding to lifetimes of nanoseconds or longer. Lepton colliders provide a clean environment for LLP searches. This study employs full simulation data to investigate LLPs produced in Higgs decays via the process e+e−→ZH, where each LLP decays...

We conduct a detailed Monte Carlo study of the process e⁺e⁻ → ZH at the CEPC. The analysis focuses on final states where the Z boson decays either invisibly or into charged leptons, while the Higgs boson decays hadronically through H → bb̄, cc̄, gg and ss̄. To distinguish among hadronic final states, we apply advanced jet-tagging methods based on ParticleNet, Particle Transformer, and the...

The decay $H \rightarrow Z\gamma$ is a rare process predicted by the Standard Model that has not yet been individually observed by either ATLAS or CMS. It proceeds through loop diagrams and is therefore highly sensitive to potential effects of new physics. As such, the search for $H \rightarrow Z\gamma$ provides an important window into physics beyond the Standard Model.
During Run 3, the...
