On the Mixing Amplitude of J/ψ and Vector Glueball O
نویسندگان
چکیده
We study the mixing angle θOψ and mixing amplitude fOψ of J/ψ and vector glueball O, in the framework of potential models of heavy quarks and constituent gluons. While the state vectors of J/ψ and O are constructed from the wave functions of few-body Schroedinger equations, the mixing dynamics is governed by perturbative QCD.We obtain a value of the mixing angle of | tan θOψ| ≈ 0.015 and the mixing amplitude of |fOψ(mOψ)| ≈ 0.008 GeV, which is compatible with phenomenological analysis.

Decays 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 کاملGlueballs: Charmonium Decay and p̄p Annihilation
The vector glueball O, made of 3 valence gluons, is expected to be “clean”: it mixes less with quarkonia, but mediates OZI violations. The recent 0 glueball candidate and the persistence of the J/ψ, ψ → ρπ puzzle suggest mO ≃ mJ/ψ, with mixing angle ∼ 2–4, hence Γ(O → ρπ, KK, ee) ∼ MeV, few keV, few eV. Lower and upper bounds on ΓO can be argued from ee → ρπ energy scan data and the condition B...
متن کاملElusive vector glueball
While theorists expect that the glueballs exist as the flavorless hadrons made of gluons alone, the predicted masses vary from lattice QCD [1] to phenomenological models such as the bag-type model [2] and a naive constituent model [3]. Experiment provided a few candidates for the ground-state glueball of J = 0 in the past, but no consensus has been reached. The glueball O of 1−− is made of thre...

We study two body decays of a scalar glueball. We show that in QCD a spin-0 pure glueball (a state only with gluons) cannot decay into a pair of light quarks if chiral symmetry holds exactly, i.e., the decay amplitude is chirally suppressed. However, this chiral suppression does not materialize itself at the hadron level such as in decays into π + π − and K + K −. We show this explicitly in two...
متن کاملPhenomenological Evidence for the Gluon Content of η and η ′
We discuss the effect of η–η mixing and of axial current anomalies on various decay processes. We describe the 2γ decays of η and η, the radiative decays of low-lying vector mesons as well as the decays η → 3π, J/ψ → ηγ and J/ψ → ηγ in one unified framework, in which they are related to the electromagnetic and strong axial current anomalies, respectively. We also discuss briefly the enhancement...
