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 reso...

Following the observation of three narrow N^(*)pentaquark states with hidden charm,P_(c)(4312),P_(c)(4440)and P_(c)(4457)[1,2],very recently,the LHCb Collaboration reported the first evidence for their strangeΛ*count...
