Quantum Field Theory of Meson Mixing
نویسنده
چکیده
We have developed a quantum field theoretic framework for scalar and pseudoscalar meson mixing and oscillations in time. The unitary inequivalence of the Fock space of base (unmixed) eigenstates and the physical mixed eigenstates is proven and shown to lead to a rich condensate structure. This is exploited to develop formulas for two flavor boson oscillations in systems of arbitrary boson occupation number. We apply these formulas to analyze the mixing of η with η′ and comment on the KL KS system. In addition, we consider the mixing of boson coherent states, which may have future applications in the construction of meson lasers.

Evidence for Parity - SU ( 3 ) Mixing in Decays of Meson Resonances
Twenty years have passed since Tomonaga made his important contribution to quantum electrodynamics. Quantum electrodynamics, although incomplete, is a triumph of quantum field theory applied to the electromagnetic interaction and has served as a model for dealing with the other particle interactions as well. The conspicuous lack of success in the domain of non-electromagnetic interactions has l...
متن کاملQuantum electrodynamics for vector mesons.
Quantum electrodynamics for rho mesons is considered. It is shown that, at the tree level, the value of the gyromagnetic ratio of the rho+ is fixed to 2 in a self-consistent effective quantum field theory. Further, the mixing parameter of the photon and the neutral vector meson is equal to the ratio of electromagnetic and strong couplings, leading to the mass difference M(rho0)-M(rho+/-) approx...
متن کاملHadronic atoms in QCD + QED November 16 , 2007
We review the theory of hadronic atoms in QCD + QED, based on a non–relativistic effective Lagrangian framework. We first provide an introduction to the theory, and then describe several applications: meson– meson, meson–nucleon atoms and meson–deuteron compounds. Finally, we compare the quantum field theory framework used here with the traditional approach, which is based on quantum–mechanical...
متن کاملMeson and tetra-quark mixing
The mixing between qq̄ meson and qq̄qq̄ tetra-quark states is examined within an effective QCD Coulomb gauge Hamiltonian model. Mixing matrix elements of the Hamiltonian are computed and then diagonalized yielding an improved prediction for the low-lying J = 0, 1 isoscalar spectra. Mixing effects were found significant for the scalar hadrons but not for the 1 states, which is consistent with the i...
متن کاملof meson , hybrid , and glueball states
The effective QCD Hamiltonian is constructed with the help of the background perturbation theory, and relativistic Feynman–Schwinger path integrals for Green's functions. The resulting spectrum displays mass gaps of the order of one GeV, when additional valence gluon is added to the bound state. Mixing between meson, hybrid, and glueball states is defined in two ways: through generalized Green'...
