Title: Analysis of $\Lambda_c$ baryons

Keywords: diquark,Lambda_c baryon spectrum, flux tube model

Abstract:
In terms of the diquark, $\Lambda_c$ baryons are classified by their spin and parity. The spectrum of $\Lambda_c$ baryons are given in a mass loaded flux tube model. Possible assignments of $\Lambda_c^+$, $\Lambda_c(2595)^+$, $\Lambda_c(2625)^+$, $\Lambda_c(2765)^+$, $\Lambda_c(2880)^+$ and $\Lambda_c(2940)^+$ are performed.
