Abstract
We construct a mass formula for the stringlike properties of mesons, based on the spectrum-generating algebra , with U(4) ⊃ SO(4) dynamic symmetry. We determine the parameters appearing in this mass formula from fits to 57 well-established mesons in the Particle Data Group summary table. The average deviation for the mass squared of these mesons is 5.7% for our fit of all meson families combined. The mass formula allows us to distinguish meson states which are not type, such as .
