Abstract :
[en] 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 $\delta u=1.172$ and $\delta d=-0.315$ in fair agreement with previous model estimations. The 5Q contribution allowed us to estimate also the strange contribution to the proton tensor charge $\delta s=- 0.011$. All those values have been obtained at the model scale $Q^2_0=0.36$ GeV^2.
