A glueball-qq filter in central production
نویسنده
چکیده
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.

متن کاملM ar 1 99 8 A search for non - qq mesons at the CERN Omega Spectrometer
The non-Abelian nature of QCD suggests that particles that have a gluon constituent, such as glueballs or hybrids, should exist. Experiments WA76, WA91 and WA102 have performed a dedicated search for these states in central production using the CERN Omega Spectrometer. Several non-qq candidates have been observed. This paper presents a study of central meson production as a function of the diff...

A partial wave analysis of the centrally produced KK and ππ systems shows that the fJ(1710) has J = 0. In addition, 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...
متن کاملImplications of the Glueball-qq filter on the 1 nonet
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-...
متن کاملThe Glueball Filter in Central Production and Broken Scale Invariance
We propose a possible explanation of the kinematical dependence of the central production of the scalar glueball candidate observed recently by the WA91 and WA102 Collaborations, and discussed by Close and Kirk, in the context of the broken scale invariance of QCD. The dependences of glueball production on the transverse momenta and azimuthal angles of the final-state protons may be related to ...
