Photoproduction of hidden-charm states in the γp→D*0Λc+ reaction near threshold

  • We report on a theoretical study of the hidden charm N*cc states in the γp→D*0Λc+ reaction near threshold within an effective Lagrangian approach. In addition to the contributions from the s-channel nucleon pole, the t-channel D0 exchange, the u-channel Λc+ exchange and the contact term, we study the contributions from the N*cc states with spin-parity JP=1/2- and 3/2-. The total and differential cross sections of the γp→D*0Λc+ reaction are predicted. It is found that the contributions of these N*cc states give clear peak structures in the total cross sections. Thus, this reaction is another new platform to study the hidden-charm states. It is expected that our model calculation may be tested by future experiments.
