Precision Study of $η^{'} \to γ π^{+} π^{-}$ Decay Dynamics

BESIII Collaboration, M. Ablikim, M. N. Achasov +431

Using a low background data sample of $9.7 \times 1 0^{5}$ $J ψ \to γ η^{'}$ , $η^{'} \to γ π^{+} π^{-}$ events, which are 2 orders of magnitude larger than those from the pr…

Improved measurements of two-photon widths of the $χ_{c J}$ states and helicity analysis for $χ_{c 2} \to γ γ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +435

Based on $448.1 \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, the decays $ψ (3686) \to γ χ_{c J}, χ_{c J} \to γ γ (J = 0, 1, 2)$ are studied. The decay branching fractio…

Measurement of branching fractions for $ψ (3686) \to γ η^{'}, γ η$ and $γ π^{0}$

M. Ablikim, M. N. Achasov, X. C. Ai +420

Using a data sample of $448 \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII storage ring, the decays $ψ (3686) \to γ η$ and $ψ(3686)\ri…

Measurement of the $D^{*} (2010)^{+} - D^{+}$ mass difference

The BaBar Collaboration

We measure the mass difference, $Δ m_{+}$ , between the $D^{*} (2010)^{+}$ and the $D^{+}$ using the decay chain $D^{*} (2010)^{+} \to D^{+} π^{0}$ with $D^{+} \to K^{-} π^{+} π^{+}$ . The data were recorded w…

Observation of $χ_{c 2} \to η^{'} η^{'}$ and $χ_{c 0, 2} \to η η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +443

Using a sample of $447.9 \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector in 2009 and 2012, we study the decays $χ_{c 0, 2} \to$ $η^{'} η^{'}$ and $η η^{'}$ . The decays $χ_{c2}\to…
