隐扇形光子的日射镜边界

Helioscope Bounds on Hidden Sector Photons

Javier Redondo

摘要:

来自太阳的假想“隐藏光子”的通量是在这样的假设下计算的,即它们只通过与普通标准模型光子的动力学混合与正常物质相互作用。由于要求奇异光子的光度小于标准光子的光度,因此混合参数的极限可以降到10^-14,这取决于隐藏光子的质量。此外,指出寻找太阳轴子的太阳望远镜对隐藏光子也非常敏感。CAST合作的最新结果被用来进一步限制低质量m<1 eV的混合参数,其中亮度约束较弱。在这种情况下,太阳隐藏的光子通量有相当大的贡献,纵向偏振的隐藏光子的低能量是不可见的,目前的日光望远镜。

英文摘要:

The flux of hypothetical "hidden photons" from the Sun is computed under the assumption that they interact with normal matter only through kinetic mixing with the ordinary standard model photon. Requiring that the exotic luminosity is smaller than the standard photon luminosity provides limits for the mixing parameter down to 10^-14, depending on the hidden photon mass. Furthermore, it is pointed out that helioscopes looking for solar axions are also very sensitive to hidden photons. The recent results of the CAST collaboration are used to further constrain the mixing parameter at low masses m<1 eV where the luminosity bound is weaker. In this regime the solar hidden photon flux has a sizable contribution of longitudinally polarized hidden photons of low energy which are invisible for current helioscopes.
