The data were recorded at root sp = 4.6 GeV with the BESIII detector and correspond to an integrated luminosity of 587 pb(-1). The. thornc spin is determined to be J = 1/2, with this value favored over the 3 2 hypothesis with a significance corresponding to more than 6 Gaussian standard deviations.eninfo:eu-repo/semantics/openAccessElectromagnetic Dipole-MomentsCharged BaryonsBent CrystalsDecayArticle2-s2.0-8510731855210.1103/PhysRevD.103.L0911019Q1103Q1WOS:000655870700012
