Study of the reactions $n ˉ p \to 2 π^{+} π^{-}$ , $2 π^{+} π^{-} π^{0}$ , and $2 π^{+} π^{-} 2 π^{0}$ using $J / ψ \to p π^{-} n ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

We report an experimental investigation of the reactions $n ˉ p \to 2 π^{+} π^{-}$ , $n ˉ p \to 2 π^{+} π^{-} π^{0}$ , and $n ˉ p \to 2 π^{+} π^{-} 2 π^{0}$ using $(10.087 \pm 0.0…

Test of local realism via entangled $Λ Λ ˉ$ system

BESIII Collaboration, M. Ablikim, M. N. Achasov +608

The non-locality of quantum correlations is a fundamental feature of quantum theory. The Bell inequality serves as a benchmark for distinguishing between predictions made by quantu…

$R (3780)$ Resonance Interpreted as the $1^{3} D_{1}$ -Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^{+} e^{-} \to$ Hadrons

M. Ablikim, M. N. Achasov, P. Adlarson +606

We report the precise measurements of the cross section of $e^{+} e^{-} \to$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study…

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^-…
