First NA62 search for long-lived new physics particle hadronic decays
The NA62 experiment at CERN, designed to measure the highly-suppressed decay $K^+\to\pi^+\nu\bar\nu$, 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 (NP) particles, including dark photons, dark scalars and axion-like particles, may be produced and reach a decay volume starting 80~m downstream of the absorber. A search for NP particles decaying in flight to hadronic final states is reported, based on a blind analysis of a sample of $1.4\times 10^{17}$ protons on target collected in dump mode in 2021.
