209. Lepton-Flavour-Violating Axion-Like Particles at Future Colliders

Marco Fedele

24/10/2026, 12:00

Axion-like particles (ALPs) with lepton-flavour-violating couplings provide a distinctive opportunity to search for new physics at future high-energy and flavour facilities. I will discuss the phenomenology of ALPs above the muon threshold, where the decay a→eμ becomes kinematically accessible and can lead to striking signatures with very small Standard Model backgrounds. I will focus on ALP...

Oral Presentation

Particle identification (PID) is important for the flavor physics analysis at future $e^+e^-$ colliders. Efficient $K/\pi$ separation can improve the reconstruction of exclusive heavy-flavor decays and suppress backgrounds from particle misidentification. A Ring Imaging Cherenkov (RICH) detector is therefore being studied to provide additional PID capability in the forward and backward regions...

32. Lattice QCD calculation of $\Xi^{-}\rightarrow\Lambda\ell^{-}\bar{\nu}_{\ell}$ semileptonic decay

04: Flavor Physics

Oral Presentation

We present the first principle calculation of $\Xi \rightarrow \Lambda$ form factors employing 2 + 1 flavor gauge ensembles with lattice spacings ranging from 0.06 to 0.1 fm and pion masses between 230 and 340 MeV.

31. Automating SU(3) Flavor-Amplitude Analysis with an AI Agent

吉 徐 (兰州大学)

04: Flavor Physics

Oral Presentation

We present an AI agent designed to automate SU(3) flavor-amplitude analyses of hadronic weak decays. Starting from a specified decay process, the agent identifies the relevant SU(3) multiplets and effective weak Hamiltonian, constructs independent invariant contractions, and converts them into amplitudes for physical decay channels. It also performs consistency checks, searches for amplitude...

210. Minimal Flavor Protection

Oral Presentation

MFP is a new flavor-symmetry spurion framework that provides minimal protection for generic new physics at the TeV scale to satisfy stringent FCNC bounds. It lies at the opposite end of the spectrum from the well-established MFV, opening up a broader landscape of flavor-safe TeV-scale models. Its defining features—maximal universality violation and flavor-charged currents—can both be...
