Abstract:

We develop a formalism for the study of mesons with the Bethe-Salpeter (BS) equation using the dual Ginzburg-Landau (DGL) theory. We introduce a new method to solve the BS equation by using the expansion method with momentum square at zero momentum. We apply this formalism to mesons in the pion channel with parity Π= - (-)J and charge conjugation C=-Π. Due to the confinement property of the gluon propagator in the DGL theory, we find the Regge behavior, M2J; that is, the mass square is proportional to the spin.
