Hidden-charm pentaquark states through current algebra:from their production to decay
《Chinese Physics C》2022年第9期62-93,共32页Hua-Xing Chen 
Supported by the National Natural Science Foundation of China (11722540, 12075019);the Jiangsu Provincial Double-Innovation Program (JSSCRC2021488);the Fundamental Research Funds for the Central Universities
There may be sevenD^((*))Σ_(c)^((*))hadronic molecular states.We construct their corresponding interpolating currents and calculate their masses and decay constants using QCD sum rules.Based on these results,we calcu...

Revisiting hidden-charm pentaquarks from QCD sum rules
《Chinese Physics C》2019年第3期72-81,共10页Jia-Bing Xiang Hua-Xing Chen Wei Chen Xiao-Bo Li Xing-Qun Yao Shi-Lin Zhu 
Supported by National Natural Science Foundation of China(11722540,11261130311);Fundamental Research Funds for the Central Universities;Foundation for Young Talents in College of Anhui Province(gxyq2018103)
We revisit hidden-charm pentaquark states P_c(4380) and P_c(4450) using the method of QCD sum rules by requiring the pole contribution to be greater than or equal to 30% in order to better that the one-pole parametriz...

Recent results from LEPS
《Chinese Physics C》2010年第9期1275-1280,共6页K.Hicks 
Supported by U.S.National Science Foundation (PHYS-0653454)
Photoproduction of baryons with strangeness,such as the Σ（1385）,Λ（1520） and possibly the Θ ＋,are described from measurements at the LEPS/SPring-8 facility in Japan.Linearly polarized photons in the energy rang...
