Instantaneous Bethe–salpeter Equation with Exact Propagators
Consequent application of the instantaneous approximation to both the interaction and all propagators of the bound-state constituents allows us to forge, within the framework of the Bethe–Salpeter formalism for the description of bound states, an instantaneous form of the Bethe–Salpeter equation with exact (i.e., full) propagators of the bound-state constituents. This instantaneous equation gen...

Abstract To understand the mechanism of the fermion pair and fermion-antifermion pair condensation,the solutions of Bethe-Salpeter equation in QED3 is examined.In the ladder appoximation our solution for the axial-scalar is consistent with Ward-Takahashi-identity for the axial vector currents.Since the massless scalar-vector sector is described by a coupled integral equation,it is difficult to ...

متن کاملGeneralized Instantaneous Bethe–Salpeter Equation and Exact Quark Propagators
Assuming all interactions to be instantaneous and the exact fermion propagator S to be approximately given by iS−1(p)= A(p2) p/−B(p2), i.e., with its scalar functions A and B depending only on p, a three-dimensional reduction of the homogeneous Bethe–Salpeter equation retaining, in contrast to the Salpeter equation, the exact propagators (crucial for, e.g., a proper incorporation of dynamical c...
