Limit on the two-photon production of the glueball candidate f(J)(2220) at the Cornell electron storage ring

Limit on the two-photon production of the glueball candidate f(J)(2220) at the Cornell electron storage ring

We use the CLEO detector at the Cornell e+ e- storage ring, CESR, to search for the two-photon production of the glueball candidate fJ(2220) in its decay to KsKs. We present a restrictive upper limit on the product of the two-photon partial width and the KsKs branching fraction, (Γγγ BKsks)fJ(2220)....

الملخص:We use the CLEO detector at the Cornell e+ e- storage ring, CESR, to search for the two-photon production of the glueball candidate fJ(2220) in its decay to KsKs. We present a restrictive upper limit on the product of the two-photon partial width and the KsKs branching fraction, (Γγγ BKsks)fJ(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 fJ(2220) has substantial glueball content.
