英文摘要	The nucleon's tensor charges (isovector g(T)(u)psilon = delta u - delta d and isoscalar g(T)(s) = delta u + delta d) are calculated using the QCD sum rules in the presence of an external tensor field. In addition to the standard quark and gluon condensates, new condensates described by vacuum susceptibilities are induced by the external field. The latter contributions to g(T)(u)psilon and g(T)(s) are estimated to be small. After deriving some simplifying formulas, a detailed sum rule analysis yields g(T)(u)psilon = 1.29 +/- 0.51 and g(T)(s) = 1.37 +/- 0.55, or delta u = 1.33 +/- 0.53 and delta d = 0.04 +/- 0.02 at the scale of 1 GeV2.
