Strange pentaquarks and excited■^(-)hyperons in■b^(-)→J/ψpK^(-)final states
《Science Bulletin》2021年第13期1256-1257,共2页Marek Karliner Jonathan L.Rosner 
The research of M.K.was supported in part by NSFC-ISF Grant No.3423/19.
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...

supported by the National Natural Science Foundation of China (NSFC);the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) through the funds provided to the Sino-German Collaborative Research Center TRR110 Symmetries and the Emergence of Structure in QCD (NSFC Grant No. 12070131001, and DFG Project-ID 196253076-TRR 110);the NSFC (11835015, and 12047503);the Grant of Chinese Academy of Sciences (XDB34030000)
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...

Observation of pentaquark states and prospectives of further studies
《Science Bulletin》2015年第17期1549-1550,共2页Cheng-Ping Shen Chang-Zheng Yuan 
The quark model based on quark–antiquark mesons and three-quark baryons has been very successful in classifying the hadrons.However,quantum chromodynamics(QCD)does not forbid the existence of exotic hadronic states w...
