Abstract

The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, including dark photons, dark scalars, and axion-like particles, may be produced in the absorber and decay in the instrumented volume beginning approximately 80 m downstream of the dump. A search for these particles decaying in flight to hadronic final states is reported, based on an analysis of a sample of \(1.4 \times 10^{17}\) protons on dump collected in 2021. No evidence of a New Physics signal is observed, excluding new regions of parameter spaces of multiple models.

在NA62中寻找弱相互作用粒子的强子衰变
欧洲核子研究中心的NA62实验能够在光束转储模式下收集数据，其中400 GeV的质子被倾倒在吸收体上。在这种配置下，新物理粒子，包括暗光子、暗标量和类轴子粒子，可以在吸收器中产生，并在倾倒体下游约80 m处开始在仪器体积中衰减。据报道，基于对2021年收集的\(1.4 \times 10^{17}\)垃圾场质子样本的分析，对这些在飞行中衰变到强子最终状态的粒子进行了搜索。没有观测到新的物理信号的证据，排除了多个模型参数空间的新区域。
