Search for sub-GeV invisible particles in inclusive decays of $J / ψ$ to $ϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +696

A search for an invisible particle, $X$ , with a mass between 0 and 0.96 $GeV / c^{2}$ , is performed in the process $J / ψ \to ϕ + X$ using $(8774.0\pm39.4)\times…

Measurement of the Inclusive Cross Sections of Prompt $J / ψ$ and $ψ (3686)$ Production in $e^{+} e^{-}$ Annihilation from $s = 3.808$ to $4.951$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The inclusive cross sections of prompt $J / ψ$ and $ψ (3686)$ production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb $^{- 1}$ of $e^{+}e^{…

Study of the decay $J / ψ \to ϕ π^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Based on $(10.09 \pm 0.04) \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector operating at the BEPCII collider, a partial wave analysis of the decay $J / ψ \to ϕ π^{0} η$ is p…
