Search for an axion-like particle in radiative $J / ψ$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +588

We search for an axion-like particle (ALP) $a$ through the process $ψ (3686) \to π^{+} π^{-} J / ψ$ , $J / ψ \to γ a$ , $a \to γ γ$ in a data sample of $(2.71 \pm 0.01) \times 1 0^{9}$ …

Observation of $e^{+} e^{-} \to π^{0} π^{0} ψ_{2} (3823)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

Using a data sample corresponding to an integrated luminosity of 11.3 $f b^{- 1}$ collected at center-of-mass energies from $4.23$ to $4.70$ ~GeV with the BESIII detector, we obse…

Observation of $χ_{c J} \to Λ Λ ˉ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

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 $χ_{c J} \to Λ Λ ˉ η$ ( $J = 0$ , 1 and 2) ar…

Search for $X (3872) \to π^{0} χ_{c 0}$ and $X (3872) \to π π χ_{c 0}$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +556

Using 9.9 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at center-of-mass energies between 4.15 and 4.30 GeV, we search for the processes $e^+e^-\toγX(3872)…
