Study of the Magnetic Dipole Transition of $J / ψ \to γ η_{c}$ via $η_{c} \to p p ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

Using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the $e^{+} e^{-}$ BEPCII collider, we present the first amplitude analysis of $J / ψ \to γ p p ˉ$ wit…

Could an axion-like particle be hidden in $η_{c} \to γ γ$ ?

Zhi-Jun Li, Zheng-Yun You, Xiao-Rui Lyu

We discuss the possibility of an axion-like particle being merged in the recent observation of $η_{c} \to γ γ$ at BESIII and find that it cannot be excluded in the current experimenta…

CP violation studies at Super Tau-Charm Facility

Hai-Yang Cheng, Zhi-Hui Guo, Xiao-Gang He +16

Charge-parity ( $C P$ ) violation in the tau-charm energy region is a promising area for sensitive tests of Standard Model (SM) predictions and searches for new, beyond the SM physi…
