Anti-Search for the Glueball Candidate f_J(2220) in Two-Photon Interactions

TL;DR

This study searches for the glueball candidate f_J(2220) in two-photon interactions using a large dataset but finds no significant signal, setting an upper limit on its production rate.

Contribution

First search for f_J(2220) decays to K^0_S K^0_S in untagged two-photon interactions with an expanded dataset, providing new upper limits.

Findings

No evidence for f_J(2220) signal was observed.

Established an upper limit on the two-photon partial width times branching fraction.

Dataset was four times larger than previous studies.

Abstract

Using 13.3 fb^{-1} of e^+e^- data recorded with the CLEO II and CLEO II.V detector configurations at CESR, we have searched for f_J(2220) decays to K^0_{S} K^0_{S} in untagged two-photon interactions. We report an upper limit on the product of the two-photon partial width and the branching fraction, Gamma_gamma gamma cdot B (f_J(2220) to K^0_{S} K^0_{S}) of less than 1.1 eV at the 95% C.L: systematic uncertainties are included. This dataset is four times larger than that used in the previous CLEO publication.
