The light vector mesons are studied within the framework of the Bethe–Salpeter equation with the vector-vector-type flat-bottom potential. The Bethe–Salpeter wavefunctions and the decay constants of the vector mesons are obtained. All the obtained results, fρ, f, and fK*, are in agreement with the experimental values, respectively.

Wavefunctions and the electromagnetic form factor of charged scalar mesons are studied with the vector–vector-type flat-bottom potential model under the framework of the spinor–spinor Bethe–Salpeter equation. The obtained results are in agreement with other theories.

The wave functions and electromagnetic form factor of charged scalar mesons are studied with a modified vector-vector flat-bottom potential model under the framework of the Schwinger–Dyson and Bethe–Salpeter equations. The obtained results agree well with other theories.
