The scalar glueball mass in Regge phenomenology

The author shows that linear Regge trajectories for mesons and glueballs, and the cubic mass spectrum associated with them, determine a relation between the masses of the {rho} meson and the scalar glueball, M(0{sup ++}) = 3/{radical}2 M({rho}), which implies M(0{sup ++}) = 1620 {+-} 10 MeV. He also discusses a relation between the masses of the scalar and tensor glueballs, M(2{sup ++}) = {radical}2 M(0{sup ++}), which implies M(2{sup ++}) = 2290 {+-} 15 MeV
