光子-光子散射教程

Photon-photon scattering: a tutorial

Yi Liang, Andrzej Czarnecki

摘要:

长期建立的低能光子-光子散射的结果,伽玛伽玛->伽玛伽玛,最近受到质疑。我们分析了这种说法,并证明它与经验不一致。我们证明了这个错误源于对发散积分的错误操作,并讨论了与最近另一个关于希格斯玻色子衰变为两个光子的说法的联系。我们展示了一个简单的方法,正确计算低能量的伽马-伽马散射。

英文摘要:

Long-established results for the low-energy photon-photon scattering, gamma gamma --> gamma gamma, have recently been questioned. We analyze that claim and demonstrate that it is inconsistent with experience. We demonstrate that the mistake originates from an erroneous manipulation of divergent integrals and discuss the connection with another recent claim about the Higgs decay into two photons. We show a simple way of correctly computing the low-energy gamma gamma scattering.
