Analytic estimates from large-Nc QCD, the chiral quark model, and next-to-leading-order chiral perturbation theory indicate the strange tensor charge in the neutron is of order 0.1 to 0.3 of the valence charges, contradicting lattice QCD values.

A strange contribution to the neutron EDM
Analytic estimates from large-Nc QCD, the chiral quark model, and next-to-leading-order chiral perturbation theory indicate the strange tensor charge in the neutron is of order 0.1 to 0.3 of the valence charges, contradicting lattice QCD values.
