标准模型双光子背景中的特征

Features in the Standard Model diphoton background

Kyrylo Bondarenko, Alexey Boyarsky, Oleg Ruchayskiy, Mikhail Shaposhnikov

摘要:

我们认为,电磁衰变的能量无味中性介子,特别是$η$,错误地识别为单光子,由于粒度的电磁量能器可能会创建凹凸状的功能,在不同的能量,包括750 GeV的双光子不变的质谱。我们讨论了什么样的额外的分析可以排除或证实这一假设。

英文摘要:

We argue that electromagnetic decays of energetic unflavoured neutral mesons, notably $η$, mis-identified as single photons due to granularity of the electromagnetic calorimeter might create bump-like features in the diphoton invariant mass spectrum at different energies, including 750 GeV. We discuss what kind of additional analysis can exclude or confirm this hypothesis.
