Abstract
We have used the chiral-quark soliton model formulated in the infinite momentum frame to investigate the octet, decuplet, and antidecuplet tensor charges up to the 5Q sector. Using flavor SU(3) symmetry we have obtained for the proton δu=1.172 and δd=-0.315 in fair agreement with previous model estimations. The 5Q contribution allowed us to estimate also the strange contribution to the proton tensor charge δs=-0.011. All those values have been obtained at the model scale Q02=0.36GeV2.
