Precision measurements of branching fractions for $ψ^{'} \to π^{0} J ψ$ and $η J ψ$

M. Ablikim, M. N. Achasov, O. Albayrak +342

We present a precision study of the $\psip\toπ^0 J/ψ$ and $η J / ψ$ decay modes. The measurements are obtained using $106 \times 1 0^{6}$ $ψ^{'}$ events accumulated with the BESIII detector a…

Determination of the number of $ψ^{'}$ event at BESIII

M. Ablikim, M. N. Achasov, D. J. Ambrose

The number of $\psp$ events accumulated by the BESIII experiment from March 3 through April 14, 2009, is determined by counting inclusive hadronic events. The result is $106.41\tim…

First observation of the isospin violating decay $J / ψ \to Λ Σ ˉ^{0} + c . c .$

M. Ablikim, M. N. Achasov, D. J. Ambrose +353

Using a sample of $(225.2 \pm 2.8) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we present results of a study of $J / ψ \to γ Λ Λ ˉ$ and report the first observ…

First observation of the M1 transition $ψ (3686) \to γ η_{c} (2 S)$

M. Ablikim, M. N. Achasov, D. J. Ambrose +356

Using a sample of 106 million ψ(3686) events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the M1 transition between the radi…
