0 Mixing of scalar glueballs and flavour - singlet scalar mesons
We discuss in detail the extraction of hadronic mixing strengths from lattice studies. We apply this to the mixing of a scalar glueball and a scalar meson in the quenched approximation. We also measure correlations appropriate for flavour-singlet scalar mesons using dynamical quark configurations from UKQCD. This enables us to compare the results from the quenched study of the mixing with the d...
متن کاملHadronic D Decays Involving Scalar Mesons
The nonleptonic weak decays of charmed mesons into a scalar meson and a pseudoscalar meson are studied. The scalar mesons under consideration are σ [or f0(600)], κ, f0(980), a0(980) and K 0 (1430). A consistent picture provided by the data suggests that the light scalars below or near 1 GeV form an SU(3) flavor nonet and are predominately the q2q̄2 states, while the scalar mesons above 1 GeV can...
متن کاملGlueballs and Hybrid Mesons
The status of non-perturbative QCD calculations for mesons with gluonic excitation is presented. Lattice results for the glueball spectrum are reviewed. For hybrid mesons, the heavy quark results are summarised and new results are presented for light quarks. Preliminary results for the spectrum of light-quark hybrid mesons indicate substantial mixing with quark model states for non-exotic J . F...

متن کاملScalar Glueballs and Friends
The f0(1500) is identified in three glueball favoured production mechanisms: pp̄ annihilation, ψ → γf0 and Central Production. The production rate for glueballs in ψ → γG has been quantified and the f0(1500) is found to be consistent with a glueball qq̄ mixture. We illustrate a remarkable property of central production where kinematic cuts appear to make a systematic separation between glueballs ...
