AI 中文总结
研究在0.1 GeV < m_a < 6 GeV质量范围,利用大型强子对撞机中高能量aγ产生,通过将ALP衰变的两个光子准直重建为单个光子,得出对类轴子粒子与光子耦合的最强限制。
AI 中文摘要
我表明,在质量范围0.1 GeV < m_a < 6 GeV内,当前对与光子耦合的类轴子粒子(ALPs)的最强限制来自大型强子对撞机中非常高能量的aγ产生。在这种情况下,来自ALP衰变的两个光子被准直并重建为单个光子。
英文摘要
I show that, in the mass range $0.1\,\text{GeV} < m_a < 6\,\text{GeV}$, the strongest current bound on axion-like particles (ALPs) coupled to photons comes from very high energy $aγ$ production at the LHC. In this regime, the two photons from the ALP decay are collimated and reconstructed as a single photon.
