英文摘要	Two new sum rules for the quark tensor charges of the nucleon are proposed, based on a relation connecting the quark transversity distributions to the quark helicity distributions and the quark model spin distributions, and on the sum rules for the quark helicity distributions. The two sum rules are useful for an estimate of the values of the quark tensor charges delta U and delta D from the measured quantities of Gamma(p), Gamma(n), g(A)/g(V) and Delta S, and two model correction factors with limited uncertainties. We predict a small value for the sum of the quark tensor charges compared with most other predictions, in analogy to the unexpectedly small quark helicity sum which gave rise to the proton 'spin puzzle'.
