Abstract

By assuming the existence of (quasi)-linear Regge trajectories for 25-plet mesons in the low-energy region, we derive a new, 14th power, meson mass relation. This relation may be reduced to a quadratic Gell-Mann-Okubo-type formula by fitting the values of the Regge slopes of these (quasi)-linear trajectories. Such a formula holds with an accuracy of similar to 2% for vector mesons, and also suggests that the quantumnumber I(J(p)) = 1/2 (2(+)) should be assigned to both the B-J(5732) and B-sJ(5850) mesons discovered recently. We also discuss reasons forthe failure of group theory to produce correct mass relations for heavy quarkonia.
