“…For excited baryons this symmetry is broken. However, based on the observation that excited states can be approximately classified as SU(2N f ) multiplets, considerable efforts have previously been made to analyze the excited states belonging to the [70, 1 − ] multiplet (N = 1 band) in the large N c limit [ 10,11,12,13,14,15,16,17,18,19,20], with obvious success.…”
