Determination of spin-parity quantum numbers of X(2370) as $0^{-+}$ from $J / ψ \to γ K_{S}^{0} K_{S}^{0} η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +616

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, a partial wave analysis of the decay $J / ψ \to γ K_{S}^{0} K_{S}^{0} η^{'}$ is performed…

Observation of the Anomalous Shape of $X (1840)$ in $J / ψ \to γ 3 (π^{+} π^{-})$ Indicating a Second Resonance Near $p p ˉ$ Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events, which is about 45 times larger than that was previously analyzed, a further investigation on the $J/ψ\rightarrow γ3(π^+π^-…

$Λ_{c}^{+}$ polarimetry using the dominant hadronic mode

LHCb collaboration

The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of t…
