Observation of $η_{c} \to p p ˉ η$ via $ψ (3686) \to γ p p ˉ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

The decay $η_{c} \to p p ˉ η$ is observed for the first time with a significance of exceeding $10 σ$ . It is found by analyzing $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events accumu…

Observation and branching fraction measurements of $J / ψ \to p p ˉ K_{S}^{0} K_{S}^{0}$ and $ψ (3686) \to p p ˉ K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events and $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the fi…

Unexpected large relative strong phase and search for isospin breaking and $C P$ asymmetries in $J/ψ\to K^*(892)\bar K

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

Using a direct scan of 26 energy points near the $J / ψ$ resonance, we perform the first measurement of the relative phase $ϕ_{γ, 3 g}$ between the strong and electromagnetic amplitud…

Updated measurement of the branching fraction of $D_{s}^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Using a dataset of 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
