Study of the Dalitz decay $J / ψ \to e^{+} e^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +507

We report corrected results on a study of the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} η$ and search for di-electron decays of a light dark gauge boson ( $γ^{'}$ ) in $J / ψ \to γ^{'} η$ w…

Test beam results with prototypes for the new Cylindrical GEM Inner Tracker of the BESIII experiment

L. Lavezzi, M. Alexeev, A. Amoroso +49

A cylindrical GEM tracker is under construction in order to replace and improve the inner tracking system of the BESIII experiment. Tests with planar chamber prototypes were carrie…

Study of $η (1475)$ and $X (1835)$ in radiative $J / ψ$ decays to $γ ϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +428

The decay $J / ψ \to γ γ ϕ$ is studied using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector. Two structures around 1475 MeV/c $^{2}$ and 1835 MeV/c…

Search for a strangeonium-like structure $Z_{s}$ decaying into $ϕ π$ and a measurement of the cross section $e^{+} e^{-} \to ϕ π π$

M. Ablikim, M. N. Achasov, S. Ahmed +432

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 108 pb $^{- 1}$ collected with the BESIII detector at a center-of-mass energy of 2.125 GeV…
