中性系统的长程电磁效应与有效场论

Long Range Electromagnetic Effects involving Neutral Systems and Effective Field Theory

Barry R. Holstein

摘要:

我们分析了有自旋和无自旋的大质量粒子的电磁散射,其中一个粒子(或两者)是电中性的。利用有效场论的方法,我们分离出了主要的长距离效应,包括经典的和量子力学的。对于无自旋系统,结果与先前通过更精细的色散方法获得的结果相同。然而,我们也发现新的结果,如果一个或两个粒子携带apin。

英文摘要:

We analyze the electromagnetic scattering of massive particles with and without spin wherein one particle (or both) is electrically neutral. Using the techniques of effective field theory, we isolate the leading long distance effects, both classical and quantum mechanical. For spinless systems results are identical to those obtained earlier via more elaborate dispersive methods. However, we also find new results if either or both particles carry apin.
