论文摘要
我们得出了完全显式运动方程和相关的约束集，描述了在恒定电磁背景下带电的Spin-3/2巨大状态的平坦时空中的传播。为此，我们在开放式超弦的第一个大规模级别为物理费米尼田提供了拉格朗日。我们首先编写一个紧凑的拉格朗日语，允许简单地推导运动方程和约束。然后，给出了另一个直接产生一个脱钩的方程系统，尽管不同旋转的磁场看起来与拉格朗日的水平相结合。
We derive fully explicit equations of motion, and the associated set of constraints, describing the propagation in a flat space-time of a charged spin-3/2 massive state in a constant electromagnetic background. For this purpose, we provide the Lagrangian for the physical fermionic fields in the first massive level of the open superstring. We first write a compact Lagrangian, allowing a simple derivation of the equations of motion and constraints. Then another one is given that yields directly a decoupled system of equations, though the fields of different spins look coupled at the level of the Lagrangian.
