Implications of the Glueball-qq filter on the 1 nonet
نویسندگان
چکیده
The application of our glueball-qq̄ filter to the centrally produced KK̄π system shows that the f1(1285) and f1(1420) have the same behaviour; namely consistent with the f1(1420) being the partner to the f1(1285) in the P1 nonet of axial mesons. We determine a flavour singlet-octet mixing angle of ∼ 50 for this nonet and highlight that the existence of the supposed f1(1510) needs confirmation. e-mail: [email protected] e-mail: [email protected]

Unquenching the scalar glueball
Computations in the quenched approximation on the lattice predict the lightest glueball to be a scalar in the 1.5−1.8 GeV region. Here we calculate the dynamical effect the coupling to two pseudoscalars has on the mass, width and decay pattern of such a scalar glueball. These hadronic interactions allow mixing with the qq scalar nonet, which is largely fixed by the well-established K 0(1430). T...
متن کاملIs f0(1500) a scalar glueball?
Following the discovery of two new scalar mesons, f0(1370) and f0(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being QQ mesons. We show instead that f0(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0 QQ̄ nonet. Tests of this hypothesis include t...
متن کاملA glueball-qq filter in central production
A study of central meson production as a function of the difference in transverse momentum (dPT ) of the exchanged particles shows that undisputed qq mesons are suppressed at small dPT whereas the glueball candidates are enhanced and that the production cross section for different resonances depends strongly on the azimuthal angle between the two outgoing protons.

We show that two nonets and a glueball provide a consistent description of data on scalar mesons below 1.7 GeV. Above 1 GeV the states form a conventional qq̄ nonet mixed with the glueball of lattice QCD. Below 1 GeV the states also form a nonet, as implied by the attractive forces of QCD, but of more complicated nature. Near the center they are (qq)3̄(q̄q̄)3 in S-wave, with some qq̄ in P-wave, but ...
