In this work, we treat Λ c (2910) + and Λ c (2940) + as the conventional udc cores dressed with the D * N channel. We provide a possible interpretation to both Λ c (2910) + and Λ c (2940) + within the same framework. In the study, we consider not only the effects between the conventional triquark core and the D * N channel but also the D * N-D * N interactions. The mass of Λ c state with J P = 1/2 − is larger than that with J P = 3/2 − in this unquenched picture, which is very different from the prediction of the conventional quenched quark model. Based on the mass spectrum, the spin-parity of Λ c (2940) + is more likely to be 1/2 − while Λ c (2910) + prefers 3/2 − . We look forward to the future experiments can test our results with more precise experimental data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
