NUCLEON TENSOR CHARGES IN THE SU(2) CHIRAL QUARK-SOLITON MODEL

We investigate the singlet g(T)((0)) and isovector g(T)((3)) tensor ch arges of the nucleon, which are deeply related to the first moment of the leading twist transversity quark distribution h(1)(x), in the SU(2 ) chiral quark-soliton model. With rotational O(1/N-c) corrections tak en into account, we obtain g(T)((0))=0.69 and g(T)((3))=1.45 at a low normalization point of several hundreds MeV. Within the same approxima tion and parameters the model yields g(A)((0))=0.36, g(A)((3))=1.21 fo r axial charges and a correct octet-decuplet mass splitting. We show h ow the chiral quark-soliton model interpolates between the nonrelativi stic quark model and the Skyrme model.
