93. T-odd asymmetry in radiative hadronic tau decays

Zhi-Hui Guo (Hebei Normal University)

19/08/2022, 14:25

I will first discuss the hadronic contributions to the $\tau \to \pi \pi \gamma \nu$ process. Distinct hadron effects are revealed in different two-particle invariant mass spectra. I will then focus on the T-odd asymmetry from the radiative two-pion decays and intriguing non-vanishing asymmetry distributions are predicted, which may provide useful guidelines to future measurements at Belle-II...

101. Probing the new physics through the exclusive decay of Higgs and Z boson

Bin Yan

The rare decays of the Higgs and Z bosons to a vector quarkonium and a photon have been widely studied, especially for the exclusive decay from the Higgs boson since it could be used to constrain the light quark Yukawa coupling and its CP violation. In this talk, I will discuss the possibility to probe the other new physics effects through these rare decay. We demonstrate that the rare decays...

62. Recent results from the SND experiment at the VEPP-2000 collider

Dmitriy Kovrizhin (Budker Institute of Nuclear Physics)

The Spherical Neutral Detector (SND) collects data at the VEPP-2000 $e^+e^-$ collider in Novosibirsk. In this talk we present the latest SND results on study of exclusive processes of $e^+e^-$ annihilation into hadrons at c.m. energies below 2 GeV. In particular, we discuss the measurement of the $e^+e^- \to \pi^+\pi^-$ cross section in the energy range $0.53 - 0.88~\rm GeV$, the measurement...
