Abstract
The NA62 experiment at CERN SPS is designed to study the $K^+\to\pi^+\nu\bar\nu$ decay. After collecting data in 2016, 2017, and 2018, the experiment has resumed data taking in 2021 and has received approval for operations until the onset of LS3. The first search for the lepton number violating decay $K^+\to\pi^0\pi^-\mu^+ e^+$ and lepton flavour violating decays $K^+\to\pi^0\pi^+\mu^+ e^-$ , $K^+\to\pi^0\pi^+\mu^- e^+$ is reported. More recent results from NA62 analyses of $K^+\to\pi^+\gamma\gamma$ and $\pi^0\to e^+e^-$ decay are also reported. Additionally, the search for New Physics in the data collected during the beam-dump mode in 2021 will be discussed.
