Quark-antiquark composite systems: the Bethe–Salpeter equation in the spectral-integration technique
The Bethe–Salpeter equations for the light-quark composite systems, qq̄, are written in terms of spectral integrals. For the qq̄-mesons characterized by the mass M , spin J and radial quantum number n, the equations are presented for the following (n,M2)trajectories: πJ , ηJ , aJ , fJ , ρJ , ωJ , hJ and bJ .
متن کاملQuark-antiquark composite systems: the Bethe–Salpeter equation in the spectral-integration technique in case of different quark masses
The Bethe–Salpeter equations for the quark-antiquark composite systems with different quark masses, such as qs̄ (with q = u,d), qQ̄ and sQ̄ (with Q = c,b), are written in terms of spectral integrals. For mesons characterized by the mass M , spin J and radial quantum number n, the equations are written for the (n,M2)-trajectories with fixed J . The mixing between states with different quark spin S ...
متن کاملMesons with a light quark-antiquark pair and the Bethe-Salpeter equation
The light quark-antiquark scattering Green's function is considered near a meson resonance peak. The Bethe-Salpeter equation is used to write formal expressions for the resonance width/mass ratio. Arguments are made concerning to what extent this ratio can be calculated perturbatively, and an upper bound is placed on the growth of this ratio as a function of radial excitation. Certain mesons an...
متن کاملQuark-antiquark Bethe-salpeter Formalism, Spectrum and Regge Trajectories
Starting from a path integral representation of appropriate 4-point and 2-point gauge invariant Green functions and from the ”Modified Area Law” model , a qq̄ Bethe-Salpeter like equation and a related Schwinger-Dyson equation can be obtained. From such equations an effective relativistic Hamiltonian can be derived by standard methods and then applied to the determination of the meson spectrum ....
متن کاملExact-propagator Instantaneous Bethe–salpeter Equation for Quark–antiquark Bound States
Recently an instantaneous approximation to the Bethe–Salpeter formalism for the analysis of bound states in quantum field theory has been proposed which retains, in contrast to the Salpeter equation, as far as possible the exact propagators of the bound-state constituents, extracted nonperturbatively from Dyson–Schwinger equations or lattice gauge theory. The implications of this improvement fo...
