Mass spectra and Regge trajectories of light mesons in the relativistic quark model

Understand

Masses of the ground, orbitally and radially excited states of quark-antiquark mesons composed from the light (u,d,s) quarks are calculated within the framework of the relativistic quark model based on the quasipotential approach.

• The relativistic treatment of the light quark dynamics results in mass spectra which agree well with available experimental data for the masses of the most well-established states.
• The Regge trajectories for angular and radial excitations are constructed, and their linearity, parallelism and equidistance are verified.
• The assignment of experimentally observed light mesons to particular Regge trajectories is based on their masses and quantum numbers.
