We present a generating functional producing quark wave functions of all Fock states in the octet, decuplet and antidecuplet baryons in the mean field approximation, both in the rest and infinite momentum frames. In particular, for the usual octet and decuplet baryons we get the SU (6)‐symmetric wave functions for their 3‐quark component but with specific corrections from relativism and from additional quark‐antiquark pairs. For the exotic antidecuplet baryons we obtain the 5‐quark wave function.
