Doubly charmed pentaquark states with strangeness
Wei Chen, Feng-Bo Duan, Zi-Yan Yang +3
In this work, we have studied the mass spectra of doubly charmed pentaquark states with strangeness by using the method of QCD sum rules. We use the parity projected sum…

Light hybrid baryons in QCD sum rules
Wei Chen, Qi-Nan Wang, Ding-Kun Lian +4
We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the low…

Interpreting the and as light tetraquark states
Qi-Nan Wang, Ding-Kun Lian, Wei Chen
Inspired by the states and reported by the BESIII Collaboration, we systematically investigate the mass spectra of light compact tetraquark states with configur…
