Abstract

In this study, we analyze the strong decays of singly charmed baryons into another singly charmed baryon and a light pseudo scalar meson by means of heavy hadron chiral perturbation theory (HHChPT) which combines heavy quark symmetry with chiral symmetry. HHChPT worked excellently for describing the strong decays of 1S-wave charmed baryons. The strong decay widths of well-established singly charmed baryons are well reproduced. Further, the strong decay width of 1P states are calculated in this approach by using the calculated masses in the relativistic flux tube (RFT) model. By analysing the mass spectra from the RFT model with strong decays in HHChPT, we investigate the spin-parity assignments. We identify Σ_c(2800) and Ξ_c(2939) as 1P-wave states having J^P=(3)/(2)^-.
