Analysis of the heavy quarkonium states hc and hb with QCD sum rules
Abstract
In this article, we take the tensor currents 
to interpolate the P-wave spin-singlet heavy quarkonium states hQ, and study the masses and decay constants with the Borel sum rules and moments sum rules. The masses and decay constants from the Borel sum rules and moments sum rules are consistent with each other, the masses are also consistent with the experimental data. The heavy quarkonium states hQ couple potentially to the tensor currents 
, and have the quark structure ϵijkξ†σkζ besides the quark structure 
.
