在ATLAS和CMS上用数据搜索寻找类轴子粒子

Searching for axion-like particles with data scouting at ATLAS and CMS

Simon Knapen, Soubhik Kumar, Diego Redigolo

摘要:

我们调查的物理情况下,一个专门的分子水平的分析非常低的质量双光子共振在ATLAS和CMS,并介绍了一个新的光子隔离标准。这大大提高了对轻粒子的接受度,但代价是标准模型背景稍大。我们展示了这样的分析可能会产生新的实验覆盖率的轴子粒子的质量低于15 GeV,弥合差距的区域覆盖的香料工厂。

英文摘要:

We investigate the physics case for a dedicated trigger-level analysis for very low mass diphoton resonances at ATLAS and CMS and introduce a new photon isolation criterion. This greatly increases the acceptance for light particles at the expense of a somewhat larger Standard Model background. We show how such an analysis would likely yield new experimental coverage for axion-like particles for masses below 15 GeV, bridging the gap with the region covered by flavor factories.
