37. We note that this does not necessarily mean that only constituent quarks are involved in the collisions. We recall that the SU(6) baryon wave function is a result of the following requirements: A baryon is a composite of three spin-(Formula presented) objects (the quarks), and these three quarks form a color singlet (and thus have a completely antisymmetric color wave function) so that their flavor and spin wave functions have to be completely symmetric. Hence, the validity of such wave functions in describing the relationship between the spins of the fragmenting quarks and that of the produced baryon may imply that these quarks first evolve into constituent quarks and then combine into a baryon. It can also imply that they first combine to form the (Formula presented) Fock state of the baryon and then evolve into a complete physical baryon, and so on. Both possibilities are consistent with the presently popular fragmentation models.
