B. Silvestre-brac et al., Universality of Regge and vibrational trajectories in a semiclassical model - art. no. 014019., PHYS REV D, 5901(1), 1999, pp. 4019
The orbital and radial excitations of light-light mesons are studied in the
framework of the dominantly orbital state description. The equation of mot
ion is characterized by a relativistic kinematics supplemented by the usual
funnel potential with a mixed scalar and vector confinement. The influence
of finite quark masses and potential parameters on Regge and vibrational t
rajectories is discussed. The case of heavy-light mesons is also presented.
