39. The linear Regge behavior for light mesons can be obtained in the quark model; for example, in models with linear confinement and relativistic kinematics, the mass of q̄q states with orbital angular momentum and radial quantum number n is given by the expression: M2n+2+34; see P. Cea, P. Colangelo, G. Nardulli, G. Paiano, and G. Preparata, Phys. Rev. D 26, 1157 (1982); PRVDAQ 0556-2821 10.1103/PhysRevD.26.1157
