Helicity amplitude analysis of $χ_{c J} \to ϕϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

Using (447.9 $\pm$ 2.3) million $ψ$ (3686) events collected with the BESIII detector, the decays of $χ_{c J} \to ϕϕ$ ( $J$ =0, 1, 2) have been studied via the decay $ψ(3686)\ri…

Study of electromagnetic Dalitz decays $χ_{c J} \to μ^{+} μ^{-} J / ψ$

M. Ablikim, M. N. Achasov, S. Ahmed +449

Using $4.48 \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector, we search for the decays $χ_{c J} \to μ^{+} μ^{-} J / ψ$ through the radiative decays $ψ(3686) \r…

Observation of $χ_{c J} \to 4 K_{S}^{0}$

M. Ablikim, M. N. Achasov, S. Ahmed +461

By analyzing $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $χ_{c J} \to 4 K_{S}^{0}$ ( $J = 0, 1, 2$ ) are obser…

Observation of OZI suppressed decays $χ_{c J} \to ω ϕ$

M. Ablikim, M. N. Achasov, S. Ahmed +462

Decays $χ_{c J} (J = 0, 1, 2) \to ω ϕ$ are studied using $(448.1 \pm 2.9) \times 1 0^{6} ψ (3686)$ events collected with the BESIII detector in 2009 and 2012. In addition to the previously est…

Measurement of the matrix elements for the decays $η^{'} \to η π^{+} π^{-}$ and $η^{'} \to η π^{0} π^{0}$

M. Ablikim, M. N. Achasov, S. Ahmed +436

Based on a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector, the matrix elements for the decays $η^{'} \to η π^{+} π^{-}$ and $η^{'} \to η π^{0} π^{0}$ …

Observation of the Dalitz Decay $η^{'} \to γ e^{+} e^{-}$

M. Ablikim, M. N. Achasov, X. C. Ai +410

We report the first observation of the Dalitz decay $η^{'} \to γ e^{+} e^{-}$ , based on a data sample of 1.31 billion $J / ψ$ events collected with the BESIII detector. The $η^{'}$ mesons are pr…

Evidence for the Direct Two-Photon Transition from $ψ (3686)$ to $J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +354

The two-photon transition $ψ (3686) \to γ γ J / ψ$ is studied in a sample of 106 million $ψ (3686)$ decays collected by the BESIII detector. The branching fraction is measured to be $(3.1\…
