Abstract

A quantity called stickiness is introduced which should be largest for J not equal to 0 glueballs and can be measured in two photon scattering and radiative J/psi decay. An argument is reviewed suggesting that light J = 0 glueballs may have large couplings to two photons. The analysis of radiative decays of eta and eta' is reviewed and a plea made to desist from false claims that they are related to GAMMA(..pi../sup 0/ ..-->.. ..gamma gamma..) by SU(3) symmetry. It is shown that two photon studies can refute the difficult-to-refute hypothesis that xi(2220) or zeta(8320) are Higgs bosons. A gallery of rogue resonances and resonance candidates is presented which would usefully be studied in ..gamma gamma.. scattering, including especially the low mass dipion. 34 references.

Search for two-photon production of f{sub J}(2220)/{xi}(2230) at CLEO

Journal Article Galik, Richard - AIP Conference Proceedings

We use the CLEO detector at the Cornell e{sup +}e{sup -} storage ring, CESR, to search for the two-photon production of the glueball candidate f{sub J}(2220) in its decay to K{sub s}K{sub s}. We present a restrictive upper limit on the product of the two-photon partial width and the K{sub s}K{sub s} branching fraction, {gamma}{sub {gamma}}{sub {gamma}}{center_dot}B{sub K{sub s}}{sub K{sub s}} for this narrow resonance. We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f{sub J}(2220) hasmore » substantial glueball content.« less

Limit on the Two-Photon Production of the Glueball Candidate f(J) (2220) at CLEO

Technical Report Jessop, Colin

We use the CLEO detector at the Cornell e{sup +}e{sup -} storage ring, CESR, to search for the two-photon production of the glueball candidate f{sub J} (2220) in its decay to K{sub s}K{sub s}. We present a restrictive upper limit on the product of the two-photon partial width and the K{sub s}K{sub s} branching fraction, ({Lambda}{sub {gamma}{gamma}}{Beta}{sub K{sub s}K{sub s}}){sub f{sub J}(2220)}. We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f{sub J}(2220) has substantial glueball content.

Journal Article Alam, M; Athar, S; Ling, Z; ... - Physical Review Letters

The CLEO II detector at the e{sup +}e{sup {minus}} storage ring CESR has been used to search for two-photon production of the f{sub J}(2220) decaying into {pi}{sup +}{pi}{sup {minus}} . No evidence for a signal is found in 4.77 fb{sup {minus}1} of data and a 95{percent} C.L. upper limit on [{Gamma}{sub {gamma}{gamma}}B{sub {pi}{sup +}{pi}{sup {minus}}}]{sub f{sub J}( 2220)} of 2.5thinspthinspeV is set.

We present a restrictive upper limit on the product of the two-photon partial width and the K{sub S}K{sub S} branching fraction for this narrow resonance.
