摘要
以自旋为2的Bargmann-Wigner方程的严格解为基础,进一步计算自旋为2的粒子的投影算符和传播子,验证了Behrends和Fronsdal所构造的自旋为2的投影算符的正确性,在坐标表象和动量表象中导出了自旋为2的费曼传播子的表达式.
Based on the solution of the Bargmann-Wigner equation for spin 2, a direct derivation of the projection operator and propagator for spin 2 is presented. The explicit form of the spin 2 projection operator constructed by Behrends and Fronsdal is confirmed, the commutation rules and a general expression for the Feynman propagator for a free particle of spin 2 are deduced.
