Study of J/psi->eta phi pi+pi- at BESIII

M. Ablikim, M. N. Achasov, X. C. Ai +402

Based on a sample of $2.25 \times 1 0^{8} J / ψ$ events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay $J / ψ \to η ϕ π^{+} π^{-}$ . The…

Precision measurement of the $D^{* 0}$ decay branching fractions

M. Ablikim, M. N. Achasov, X. C. Ai +405

Using 482 pb $^{- 1}$ of data taken at $s = 4.009$ GeV, we measure the branching fractions of the decays of $D^{* 0}$ into $D^{0} π^{0}$ and $D^{0} γ$ to be $\BR(D^{*0} \to D^0π^0)=(65.5…
