A light pseudo-scalar that is copiously produced at the LHC may still be allowed by present searches. While masses above 65 GeV are effectively covered by di-photon searches, the lower mass window can be tested by a new search for boosted di-tau resonances. We test this strategy on a set of composite Higgs models with top partial compositeness, where most models can be probed with an integrated luminosity below 300 .
大型强子对撞机大量产生的一种轻赝标量粒子目前的搜索可能仍然允许存在。虽然双光子搜索有效地覆盖了高于65 GeV的质量范围，但较低质量窗口可通过对增强型双陶共振的新搜索来检验。我们在一组具有顶部分复合性的复合希格斯模型上测试了这一策略，其中大多数模型可以在积分光度低于300 时进行探测。
