Laser极化实验的发现潜力

The Discovery Potential of Laser Polarization Experiments

Markus Ahlers, Joerg Jaeckel, Andreas Ringwald

摘要:

目前,许多实验正在寻找真空磁双折射和二向色性,即偏振光在真空中沿横向磁场传播时的色散和吸收特性。在本文中,我们计算了标准模型对这些特征的贡献,从而阐明了这些实验在寻找新物理学中的发现潜力。我们讨论了标准模型对二向色性信号贡献的三个主要来源:光子分裂、中微子对产生和引力子产生。

英文摘要:

Currently, a number of experiments are searching for vacuum magnetic birefringence and dichroism, i.e. for dispersive and absorptive features in the propagation of polarized light along a transverse magnetic field in vacuum. In this note we calculate the Standard Model contributions to these signatures, thereby illuminating the discovery potential of such experiments in the search for new physics. We discuss the three main sources for a Standard Model contribution to a dichroism signal: photon splitting, neutrino pair production and production of gravitons.
