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 next generation of neutrino experiments presents unprecedented opportunities to address key questions in particle physics and astrophysics. This talk will summarise recent contributions made in two flagship international experiments: JUNO, a 20,000-ton liquid scintillator detector that has recently entered full data-taking in China, and TRIDENT, a next-generation deep-sea Cherenkov...
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...
The Jiangmen Underground Neutrino Observatory, with the world's largest liquid scintillator detector, has recently completed the detector construction and started data taking. The main purpose of the experiment is to determine the neutrino mass ordering and perform a precision measurement of the neutrino oscillation parameters. Muon secondary particles play an important role in data analysis....
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...
Optical imaging of alpha tracks in scintillators have been demonstrated in recent years. The imaging of particle tracks has potentials in rare event searches, such as the neutrinoless double-beta decay search. This talk presents the observation and data analyses of alpha particle tracks in a GAGG crystal scintillator using a scientific CMOS camera mounted on an optical microscope. Results on...
DarkSHINE is a newly proposed fixed-target experiment initiative to search for the invisible decay of Dark Photon via missing energy/momentum signatures, based on the high repetition rate electron beam to be deployed/delivered by the Shanghai High repetition rate XFEL and Extreme light facility (SHINE). The DarkSHINE experiment has recently conducted a series of prototype tests and explored...
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...
