摘要

Induced tensor charge of the nucleon $g_T$ , which originates from G-parity violation, is evaluated from QCD sum rules. We find that $g_T/g_A$ with $g_A$ being the axial charge is $-$ 0.0152 $\pm$ 0.0053 which is proportional to u-d quark mass difference. This result is small compared to preliminary analysis of the experiment, but is consistent with the estimate in the MIT bag model.
