Quantum 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 کاملBeables for Quantum Electrodynamics
We show that it is possible to obtain a realistic and deterministic model, based on a previous work of John Bell, which reproduces the experimental predictions of the orthodox interpretation of quantum electrodynamics. P.A.C.S.: 03.65.Ta; 03.70.+k
متن کاملMassless and Massive Vector Goldstone Bosons in Nonlinear Quantum Electrodynamics
The spontaneous Lorentz invariance violation (SLIV) developing in QED type theories with the nonlinear four-vector field constraint A μ = M (where M is a proposed scale of the Lorentz violation) is considered in the case when the internal U(1) charge symmetry is also spontaneously broken. We show that such a SLIV pattern induces the genuine vector Goldstone boson which appears massless when the...
متن کاملSymmetries for Vector and Axial - Vector Mesons ∗
We discuss the possible symmetries of the effective lagrangian describing interacting pseudoscalar-, vector-, and axial-vector mesons. Specific choices of the parameters give rise to an [SU(2) ⊗ SU(2)] symmetry. This symmetry can be obtained either á la Georgi, with all states in the spectrum remaining massless, or in a new realization, implying decoupling of the pseudoscalar bosons from degene...
متن کاملOne loop corrections to quantum hadrodynamics with vector mesons
The renormalized elastic ππ scattering amplitude to one loop is calculated in the chiral limit in the σ model and in a Quantum Hadrodynamic model (QHD-III) with vector mesons. It is argued that QHD-III reduces to the linear σ model in the limit that the vector meson masses become large. The pion decay constant is also calculated to 1-loop in the σ model, and at tree level in QHD-III; it is show...
