Abstract :
We calculate gA(3) in the chiral quark-soliton model (or equivalently in semibosonized Nambu-Jona-Lasinio model) in the limit of small and large soliton size. In small soliton limit we recover the results of the constituent quark model. The agreement between the two models is achieved due to the recently calculated 1Nc contributions to gA(3) and to gA(0). In the case of gA(3) these terms arise from the time-ordering of the collective operators. For large solutons simple scaling arguments show that the 1Nc contributions vanish with the inverse power of the soluton size.
