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 کاملMixing of Pseudoscalar Mesons
η – η mixing is discussed in the quark-flavor basis with the hypothesis that the decay constants follow the pattern of particle state mixing. On exploiting the divergences of the axial vector currents – which embody the axial vector anomaly – all mixing parameters are fixed to first order of flavor symmetry breaking. An alternative set of parameters is obtained from a phenomenological analysis....
متن کاملDecays of J/ψ and ψ into vector and pseudoscalar meson and the pseudoscalar glueball-qq̄ mixing
We introduce a parametrization scheme for J/ψ(ψ′) → V P where the effects of SU(3) flavor symmetry breaking and doubly OZI-rule violation (DOZI) can be parametrized by certain parameters with explicit physical interpretations. This scheme can be used to clarify the glueball-qq̄ mixing within the pseudoscalar mesons. We also include the contributions from the electromagnetic (EM) decays of J/ψ an...
متن کاملMixing of Η-η′ Mesons in J/ψ Decays into a Vector and a Pseudoscalar Meson
The octet-singlet mixing angle θP in the pseudoscalar meson nonet is deduced from the rich set of accurate data on J/ψ decays into a vector and a pseudoscalar meson. Corrections due to non-ideal ω-φ mixing have been included for the first time and turn out to be crucial to find θP = −16.9◦±1.7◦, which is appreciably less negative than previous results coming from similar analyses. The value of ...
متن کاملModel discrimination in pseudoscalar-meson photoproduction
Article history: Received 8 March 2016 Received in revised form 22 April 2016 Accepted 21 May 2016 Available online 26 May 2016 Editor: V. Metag To learn about a physical system of interest, experimental results must be able to discriminate among models. We introduce a geometrical measure to quantify the distance between models for pseudoscalarmeson photoproduction in amplitude space. Experimen...
