Experimental study of the reaction $Ξ^{0}n\rightarrowΛΛX$ using $Ξ^{0}$-nucleus scattering

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using $(10087\pm44)\times10^{6}$$J/ψ$ events collected with the BESIII detector operating at the BEPCII storage ring in $2009$, $2012$, $2018$, and $2019$, we perform a search for the reaction $Ξ^0n\rightarrowΛΛX$, where $X$ denotes any additional final particles. Given the highly suppressed phase space for …

Observation of transverse polarization and determination of psionic form factors of the Λ hyperon at s = 3.773 GeV

M. Ablikim, M. N. Achasov, P. Adlarson, X. C. Ai et autres

Using a data sample of e + e − collision data corresponding to an integrated luminosity of 20.3 fb − 1 collected by the BESIII detector at the BEPCII collider, we present an observation of transverse polarization and a complete determination of …

Partial Wave Analysis of $e^{+}e^{-} \rightarrow π^{+}π^{-}J/ψ$ and Cross Section Measurement of $e^{+}e^{-} \rightarrow π^{\pm}Z_{c}(3900)^{\mp}$ from 4.1271 to 4.3583 GeV

BESIII Collaboration, М. Н. Ачасов, P. Adlarson, O. Afedulidis et autres

Based on 12.0 $\mathrm{fb^{-1}}$ of $e^{+}e^{-}$ collision data samples collected by the BESIII detector at center-of-mass energies from 4.1271 to 4.3583 GeV, a partial wave analysis is performed for the process $e^{+}e^{-} \rightarrow π^{+}π^{-}J/ψ$. The cross sections for the sub processes ${e^{+}e^{-}\rightarrowπ^{+}Z_{c}(3900)^{-}+c.c.\rightarrowπ^{+}π^{-}J/ψ}$, …
