论文摘要
我们在实验上证明了三叉戟过程$ e^ - \ rightarrow e^-e^+e^ - 在强的外部场中，其空间延伸与有效的辐射长度相当，从理论上讲是可以很好地理解的。该实验是在CERN进行的，探测了强场参数$χ$ 2.4的值。实验数据和使用局部恒定场近似值的实验数据和理论期望在近3个数量级的产量上表现出显着的一致性。
We demonstrate experimentally that the trident process $e^-\rightarrow e^-e^+e^-$ in a strong external field, with a spatial extension comparable to the effective radiation length, is well understood theoretically. The experiment, conducted at CERN, probes values for the strong field parameter $χ$ up to 2.4. Experimental data and theoretical expectations using the Local Constant Field Approximation show remarkable agreement over almost 3 orders of magnitude in yield.
