Search for exotic decays at NA62
Roberta Volpe
TL;DR
The NA62 experiment at CERN is optimized to search for long-lived, weakly interacting particles predicted by BSM theories, using kaon and pion decays and dump mode operation, with promising sensitivity to Dark Photons, Heavy Neutral Leptons, and Axion-Like Particles.
Contribution
This paper presents the NA62 experiment's capabilities and sensitivity estimates for detecting exotic long-lived particles beyond the Standard Model.
Findings
NA62 can effectively search for Dark Photons, Heavy Neutral Leptons, and Axion-Like Particles.
The experiment's features enhance its sensitivity to rare BSM decays.
Future data prospects could improve detection sensitivity.
Abstract
The features of the NA62 experiment at the CERN SPS (high intensity setup, trigger system flexibility, high frequency tracking of beam particles, redundant particle identification, and high-efficiency photon vetoes) make NA62 particularly suitable to search for long-lived, weakly coupled particles within Beyond the Standard Model (BSM) physics, using kaon and pion decays as well as operating the experiment in dump mode. The NA62 sensitivity for searches of Dark Photons, Heavy Neutral Leptons and Axion-Like Particles are presented, together with prospects for future data taking at the NA62 experiment.
