【Abstract】 The property of fractional spin of the O (3) nonlinear sigma model with Hopf and Maxwell-Chern-Simons (MCS) terms is studied. According to the rule of path integral quantization for a constrained Hamilton system in Faddeev-Senjanovic scheme,the system is quantized. Based on the quantal Noether theorem,we get the quantal conserved angular momentum,and the fractional spin at the quantum level of this system is presented.更多还原
