Resolving the low mass puzzle of $$\Lambda _c(2940)^+$$ Λc(2940)+
Abstract For the long standing low mass puzzle of $$\Lambda _c(2940)^+$$ Λc(2940)+ , we propose an unquenched picture. Our calculation explicitly shows that the mass of the $$\Lambda _c(2P,3/2^-)$$ Λc(2P,3/2-) state can be lowered down to be consistent with the experimental data of $$\Lambda _c(2940...
