17. Searching for new physics using rare lepton transitions

Jure Zupan (University of Cincinnati)

6/9/26, 9:30 AM

I will review how rare tau and muon transitions can be used to search for new physics. Of special interest are decays into light new physics states, that still lead to visible exotic signatures.

18. New Physics Searches at BESIII

Dr Liang Sun (Wuhan University (CN))

6/9/26, 11:00 AM

The BESIII experiment is a symmetric e+e- collider operating at c.m.
energy from 2.0 to 4.95 GeV. With the world’s largest threshold
production data set of J/ψ (10 billion), ψ(3686) (2.6 billion), and
millions of D(s) meson pairs, we are able to search for various BSM
particles (dark sector, Z', X(17), etc) produced in e+e- annihilation
and meson decay processes, as well as searching for...

19. Search for dark sector particles and other highlights from Belle II

Prof. Youngjoon Kwon (Yonsei University)

6/9/26, 11:30 AM

In this talk, we present recent results on dark sector search at Belle II experiment. In particular, we will report the searches for dark Higgs in inelastic dark matter scenario, axion-like particle searches both in ISR continuum and in B decays, and feebly-interacting particles in B decays. In addition, we will also report a few recent highlights including updates of R[D(*)] and B+ -> mu+ nu.
