摘要
在与核子相对论ＢＵＵ方程相统一的框架内，利用闭合时间回路格林函数方法导出了△粒子的相对论ＢＵＵ方程，并同时给出平均场与碰撞项的解析表达式．结果表明，核子与△粒子的ＢＵＵ方程是相互联立的．
Using the closed time-path Green's function technique,we derived the relativistic Boltzmann-Uehling-Uhlenbeck(RBUU)equation for delta distribution function within the same framework used for nucleon's.In our approach,both mean field and collision term of △'s RBUU equation are given explicitly and simultaneously.The results show that the RBUU equation for delta and for nucleon are coupled with each other.
