2026年新物理前沿与交叉科学研讨会 (NPhiS 2026)

We preset the linear cosmological evolution of inelastic self-interacting dark matter in a two-component dark sector with a small mass splitting, assuming thermal initial conditions for the two species.
We derive the coupled background and perturbation equations for inelastic conversion between the two species,
considering both power-law and velocity-saturated cross sections.

We explore the searches for axion-like particles (ALPs) at the electron-ion collider (EIC) to be built at the Brookhaven National Laboratory. We propose search strategies with the production of diphoton in both coherent (elastic) and inelastic scatterings. We found the EIC embraces the possibility to extend the existing ALP searches.

The axion solution to the strong CP problem is only as robust as the Peccei-Quinn symmetry it relies on, and quantum gravity is expected to break it. We quantify the resulting axion quality problem using principled measures of fine-tuning, and show that the cost is severe. For the QCD axion to account for the observed dark matter, Planck-suppressed symmetry-breaking operators must be absent up...

I will discuss models of fermion masses and mixing based on continuous flavour symmetries, emphasizing the phenomenology of the corresponding gauge bosons and — in the global symmetry case — the (pseudo) Nambu-Goldstone bosons arising from spontaneous symmetry breaking. Beginning with a brief overview of the Froggatt-Nielsen U(1) case, I will then focus on a realistic U(2) model. I will show...

The intersection of high energy physics and quantum information science has opened new avenues for exploring fundamental physics at high energy colliders. Future lepton colliders, characterized by their clean collision environments and precise beam controls, provide an ideal experimental platform for high energy quantum information measurement. In this talk, we present a comprehensive study of...

We propose to discuss the modular flavor model and the stabilization of single modulus field in
the Jordan frame supergravity with non-minimal scalar-curvature coupling of the form Φ(τ, τ ¯)R.
Modular invariance and positivity of the scale factor constrain stringently the form of the frame
function, consequently the Kahler potential. We discuss some general properties of scalar...
