| dc.description | A new baryonic state $Λ_{c}(2940)^{+}$ has recently been discovered by the Babar collaboration in the $D^{0}p$ channel. Later Belle collaboration also observed this state in the $Σ_c(2455)^{0,++} π^{\pm}\to Λ_{c}^{+}π^{+}π^{-}$ channel. The mass of $Λ_{c}(2940)^{+}$ is just a few MeV below the sum of $D^{*0}$ and $p$ masses suggesting a possibility that this state may be a $D^{*0} p$ molecular state. In this paper we study whether such a molecular state can be consistent with data. We find that the molecular structure can explain data and that if $Λ_c(2940)^+$ is a $D^{*0} p$ molecular state it is likely a $1/2^-$ state. Several other decays modes are also suggested to further test the molecular structure of $Λ_c^+(2940)$. | |
