论文摘要
对暗物质实验（PADME）的正电子歼灭使用了在实验室Nazionali di Frascati（LNF）的Da $φ$ ne beam-test设施的正电子束来搜索暗光子$ a'$。搜索技术研究了$ e^+e^ - \ rightarrowa'γ$ nillation中的单光子最终状态的缺失质谱，该质谱是在thin-thin-target实验中。这种方法促进了搜索新颗粒，例如长期存在的轴突状粒子，原始X玻色子和深色希格斯。该演讲说明了实验的科学计划及其第一个物理结果。特别是，显示了SM过程的横截面$ e^+e^ - \rightArrowγγ$在$ \ sqrt {s} $ = 21 meV的测量。
The Positron Annihilation to Dark Matter Experiment (PADME) uses the positron beam of the DA$Φ$NE Beam-Test Facility, at the Laboratori Nazionali di Frascati (LNF) to search for a Dark Photon $A'$. The search technique studies the missing mass spectrum of single-photon final states in $e^+e^-\rightarrow A'γ$ annihilation in a positron-on-thin-target experiment. This approach facilitates searches for new particles such as long lived Axion-Like-Particles, protophobic X bosons and Dark Higgs. This talk illustrated the scientific program of the experiment and its first physics results. In particular, the measurement of the cross-section of the SM process $e^+e^-\rightarrow γγ$ at $\sqrt{s}$=21 MeV was shown.
