QCD sum rule predictions on gluonic tetraquark states with and
Abstract: In this work, we present a systematic calculation of the mass spectrum for tetraquark hybrid states, focusing on the color configuration, within the framework of QCD sum rules. As an extension of our previous work on and states, we now construct 18 distinct interpolating currents with , , and . Using operator product expansion (OPE) techniques and including nonperturbative contributions up to dimension six, we obtain key results: for the , , and states, the predicted masses lie in the range of $7.2-7.3$ GeV, while the and states have slightly lower masses, between 6.9 and 7.1 GeV. These predictions provide strong support for the possible existence of an component within the di- structure reported by LHCb. Moreover, our analogous calculations for tetrabottom hybrid states yield mass ranges of $19.4-19.5$ GeV (for , , and ) and $19.2-19.3$ GeV (for and ), offering crucial references for future searches.
