Some mass relations for mesons and baryons in Regge phenomenology

Understand

In the quasilinear Regge trajectory ansatz, some useful linear mass inequalities, quadratic mass inequalities and quadratic mass equalities are derived for mesons and baryons.

• Based on these relations, mass ranges of some mesons and baryons are given.
• The masses of bc-bar and ss-bar belonging to the pseudoscalar, vector and tensor meson multiplets are also extracted.
• The J^P of the baryon Xi_cc(3520) is assigned to be 1/2^+.
