Spectroscopy of light N~* baryons
|
摘要
We present the masses of N baryons up to 3300 MeV. The radial and orbital excited states are determined using hypercentral constituent quark model with the first-order correction. The obtained masses are compared with the experimental results and other theoretical predictions. The Regge trajectories are also determined in(n, M~2) and(J, M~2) planes. Moreover, the magnetic moments with J~p =(1~+/2,1~-/2) are calculated. We also calculates the Nπ decay width of excited nucleons.
