■−b→J/ψΛK−衰变末态中的奇异五夸克态与■−超子激发态
Strange pentaquarks and excited■^(-)hyperons in■b^(-)→J/ψpK^(-)final states
摘要
Besides the observed quark-antiquark and three-quark states,the quark model predicts other states with integral charges,such as qqqq(tetraquarks)and qqqqq(pentaquarks).In 2015,the LHCb Collaboration observed J=wp resonances consistent with pentaquarks inΛ^(0)_(b)→J/ψwpK^(-)decays[1].
