**Solvable two-body Dirac equation as a potential model of light mesons**

**Abstract:**

The two-body Dirac equation with general local potential is reduced to the pair of ordinary
second-order differential equations for radial components of a wave function. The class of
linear + Coulomb potentials with complicated spin-angular structure is found, for which the
equation is exactly solvable. On this ground a relativistic potential model of light mesons
is constructed and the mass spectrum is calculated. It is compared with experimental data.
