Abstract：
The tensor charges of the nucleon are calculated by using the QCD Sum Rules in the external tensor field,where the nucleon interpolating field(nucleon current operator)takes the most general form,i.e.the unconventional one . Calculation includes the terms up to demension 8. All possible effects on QCD sum rule calculations of tensor charges of the nucleon by changing interpolating field and tensor susceptibilities are analysed. The calculations show that the stable solution for QCD sum rules of tensor charges of the nucleon can not be obtained by changing interpolating field and tensor susceptibilities. However,the stable behavior of the solutions for the sum rules of isovector and isoscalar tensor charges may be improved when the interpolation field takes the best one. The tensor charges of the nucleon by taking average over the so-called“sum rule window”are given.

Abstract: The tensor charges of the nucleon are calculated by using the QCD Sum Rules in the external tensor field,where the nucleon interpolating field(nucleon current operator)takes the most general form,i.e.the unconventional one . Calculation includes the terms up to demension 8. All possible effects on QCD sum rule calculations of tensor charges of the nucleon by changing interpolating field and tensor susceptibilities are analysed. The calculations show that the stable solution for QCD sum rules of tensor charges of the nucleon can not be obtained by changing interpolating field and tensor susceptibilities. However,the stable behavior of the solutions for the sum rules of isovector and isoscalar tensor charges may be improved when the interpolation field takes the best one. The tensor charges of the nucleon by taking average over the so-called“sum rule window”are given.
