摘要
以自旋为任意整数的粒子的Bargmann-Wigner方程的解为基础,在运动系中直接导出自旋为任意整数的投影算符的表达式,将低自旋投影算符理论推广到了自旋为任意整数的高自旋情形,验证了Behrends和Fronsdal所构造的投影算符的正确性。
Based on the relativistic wave functions for a particle with arbitrary integral spin in momentum and in coordinate representations , a direct derivation of the projection operators for particles of arbitrary integral spin is performed in an arbitrary frame. Thus the well-established projection operator theories that describe spins 0 and 1 have been extended to a general theory that could describe arbitrary integral spin, which confirms the formalism constructed by Behrends and Fronsdal and provides a reliable theoretical basis for the analyses of high energy physics processes.
