Quantum Field Theory of Meson Mixing
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 occup...
متن کاملPoint-Form Quantum Field Theory and Meson Form Factors
Recently we have reconsidered the quantization of relativistic field theories on a Lorentz-invariant surface of the form xμx μ = τ [1]. With this choice of the quantization surface all components of the 4-momentum operator become interaction dependent, whereas the generators of Lorentz transformations stay free of interactions – a feature characteristic for Dirac’s “point form” of relativistic ...
متن کاملCoherence of neutrino flavor mixing in quantum field theory
Several recent works have examined neutrino flavor mixing by considering the neutrino production/mixing/detection as a single process in the context of quantum field theory (QFT) [1–8]. Such a framework clarifies several conceptual difficulties associated with the familiar quantum mechanical (QM) model of the flavor mixing process (see Ref. [9] for a listing of some of these). One conceptual di...
متن کاملExploring the implications of the laws and principles of quantum physics in the field of talent (quantum theory of talent)
The issue of talent-discovering is one of the most important issues in the field of education and research that has always been a concern for educational systems. Studying the issues of identifying and guiding talented students can illuminate a large part of the activities of the executors and practitioners in order to accomplish their mission effectively. On the other hand, quantum physics has...
متن کاملLifetime of collective isospin rotations of a quantum meson field
We calculate the lifetime of the collective isospin rotating solutions which have been found recently in the case a quantum N-component meson field with exact O(N) symmetry. For this purpose we take into account the small breaking of the O(N) symmetry associated to the non vanishing mass of the pion. This term induces a coupling between collective rotations and intrinsic meson excitations. We e...
