η(′)γ in perturbative QCD
With the recent investigations of gg − η(′) transition form factor and η − η mixing scheme, we present an updated study of the radiative decays J/Ψ → η(′)γ in perturbative QCD. The decays are taken as a test ground for the gg − η(′) transition form factors and the η − η mixing scheme. The form factors are found to be working for glunic η(′) productions and the mixing angle is constrained to be ...

The radiative decays of the pseudoscalar mesons P = (π 0 , η, η ′) are of special interest as they provide an experimental window on the electromagnetic and colour chiral UA(1) anomalies. π 0 → γγ is well described by the electromagnetic UA(1) anomaly under the assumption that π 0 is a Goldstone boson for spontaneously broken chiral symmetry, but the analogous results for η ′ (η) → γγ are compl...
متن کاملMixing and Decay Constants of Pseudoscalar Mesons: Octet-Singlet vs. Quark Flavor Basis
Although η−η mixing is qualitatively well understood as a consequence of the U(1)A anomaly in QCD together with a broken SU(3)F flavor symmetry, until recently the values of decay and mixing parameters of the η and η were only approximately known, e.g. values for the octet-singlet mixing angle between −20 and −10 could be found in the literature. New experimental data, especially for the reacti...

متن کاملExclusive charmless Bs hadronic decays into η ′ and η
Exclusive charmless B s hadronic decays into η ′ and η Using the next-to-leading order QCD-corrected effective Hamiltonian, charmless exclusive nonleptonic decays of the Bs meson into η or η ′ are calculated within the generalized factorization approach. Nonfactorizable contributions are included with two different treatments. Some subtleties involved are discussed.
