Commutators in Supersymmetric CP(n-1}_{2) Model
Abstract
The supersymmetric extension of CP(n-1}_{2) model is investigated under the several gauge-fixing conditions by using the projection-operator-method of constrained dynamics. it is shown that, when the gauge-freedom is fixed, the commutation relations among the field operators contain certain quantum corrections, which can never be obtained by the quantization with the Dirac bracket. The physical interpretation for the difference between these two approaches to the quantization of constrained systems is given.
