Fully strange tetraquark states with the exotic quantum numbers JP C=0+- and 2+-
Abstract
We study the fully strange tetraquark states with the exotic quantum numbers JP C=0+- and 2+-. We construct their corresponding diquark-antidiquark interpolating currents and apply the QCD sum rule method to calculate both their diagonal and off-diagonal correlation functions. The obtained results are used to construct some mixing currents that are nearly noncorrelated, from which we extract the masses of the lowest-lying states to be M0+-=2.4 7-0.44+0.33 and M2+-=3.0 7-0.33+0.25 GeV . We apply the Fierz rearrangement to transform the diquark-antidiquark currents to be the combinations of meson-meson currents, and the obtained Fierz identities indicate that these two states may be searched for in the P -wave ϕ (1020 )f0(1710 )/ϕ (1020 )f2'(1525 )(→ϕ K K ¯ /ϕ π π ) channels.
