| 英文摘要 | The nucleon's tensor charges (isovector g(T)(upsilon) = delta u - delta d and isoscalar g(T)(a) = delta u + bd) are calculated using the QCD (quantum chromodynamics) sum rules in the presence of an external tensor field. By combining the mass sum rule of nucleon, we derive a simplified form for proton tensor charges, which gives g(T)(upsilon) = 1.27 and g(T)(a) = 1.31, or delta u = 1.29 and delta d = 0.02 at the scale of nucleon mass, with an uncertainty about 20%. |
