Analysis of the heavy quarkonium states $h_c$ and $h_b$ with QCD sum
rules
   [PDF]

Zhi-Gang Wang
In this article, we take the tensor currents to interpolate the spin-singlet
heavy quarkonium states $h_c$ and $h_b$, and calculate the masses and decay
constants using both the Borel sum rules and moments sum rules, the predictions
$M_{h_c}=3.46^{+0.12}_{-0.13}\,\rm{GeV} $ (or $3.47^{+0.13}_{-0.14}\,\rm{GeV}$)
and $M_{h_b}=9.82^{+0.12}_{-0.14}\,\rm{GeV}$ (or
$8.87^{+0.10}_{-0.10}\,\rm{GeV}$) are consistent with the experimental data.
