Amplitude analysis of $D^{+} \to K_{S}^{0} π^{+} π^{+} π^{-}$

M. Ablikim, M. N. Achasov, S. Ahmed +458

The decay $D^{+} \to K_{S}^{0} π^{+} π^{+} π^{-}$ is studied with an amplitude analysis using a data set of 2.93${\mbox{\,fb}^{-1}}$ of $e^{+} e^{+}$ collisions at the $ψ (3770)$ …

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 $h_{c} \to π^{+} π^{-} J / ψ$ via $ψ (3686) \to π^{0} π^{+} π^{-} J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +415

Using a data sample of $448.1 \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition $h_c\rightarrowπ…
