摘要
本文采用二分量的形式,利用时间平移算子和不可约核的重排列,建立二分量复标量场的等时方程。利用格林函数g_0的性质得到等时散射振幅方程。而后由矩阵元方程分离出通常两个复合玻色粒子满足的等时方程,它是一个三维方程,因此无鬼态。
The two-component forms are adopted. By using the time-displacement operators and rearranging the irreducible kernel the equal-time equation of the two-component complex scalar field is established. By using the character of the Green function g_0 the equation of equal-time scattering amplitude is obtained. Then from the equations of the matrix elements the equation of the usual two composite boson is separated, as it is a three-dimensional equation, the ghost states disappear.
