英文摘要 | We report on a theoretical study of the hidden charm N-c (c) over bar* states in the gamma p -> (D) over bar *0 Lambda(+)(c) reaction near threshold within an effective Lagrangian approach. In addition to the contributions from the s-channel nucleon pole, the t-channel D-0 exchange, the u-channel Lambda(+)(c) exchange and the contact term, we study the contributions from the N-c (c) over bar* states with spin-parity J(P) = 1/2(-) and 3/2(-). The total and differential cross sections of the gamma p -> (D) over bar *0 Lambda(+)(c) reaction are predicted. It is found that the contributions of these N-c (c) over bar* 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. |
