20 Feb 2016 | | Abstract: | Mass spectra of excited state single charmed baryons are calculated using the
hypercentral description of three body system. The baryon consist with heavy
quark c and light quarks u, d and s (with unequal masses) are studied in the
framework of QCD motivated quark model. The form of confinement potential is
hyper coloumb plus power potential with potential index $
u$, starting from
0.5 to 2.0. The first order correction to the confinement potential is also
incorporated in this approach. We are able to predict the radial as well as
orbital excited state masses of ($Sigma_{c}^{++}, Sigma_{c}^+, Sigma_{c}^0,
Xi_c^+, Xi_c^0, Lambda_c^+, Omega_c^0$) baryons. We also incorporate
spin-spin, spin-orbit and tensor interactions perturbatively in the potential.
The semi-electronic decay of $Omega_c$ and $Xi_c$ are calculated using the
spectroscopic parameters of these baryons. The computed results are compared
with other theoretical predictions as well as experimental observations. | | Source: | arXiv, 1602.6384 | | Services: | Forum | Review | PDF | Favorites | |
