“…Thanks to dedicated di-lepton and multi-track trigger lines [7], running concurrently with the main 𝐾 + → 𝜋 + 𝜈 ν trigger line, NA62 has the world's leading sensitivity to most LF/LN violating 𝐾 + decays and has already set stringent 𝐵𝑅 upper limits (UL) for a variety of processes, all listed in Tab.1. Based on results from Run 1 only, NA62 has improved on previous limits by at least a factor two up to a factor greater than O (10 2 ), depending on the process, and provided the first limit for the 𝐵𝑅(𝐾 + → 𝜋 − 𝜋 0 𝜇 + 𝑒 + ).…”

Rare kaon decays are among the most sensitive probes of both heavy and light physics beyond the Standard Model (SM) thanks to the high precision of the SM predictions, the availability of very large datasets and the relatively simple decay topologies. NA62 is the CERN multi-purpose fixedtarget kaon decay experiment, carring out a broad rare decay and hidden sector physics program. Recent NA62 searches for lepton flavor and lepton number violation and for the production of hidden sector mediators in 𝐾 + decays, along with their future prospects, are presented.

“…Thanks to auxiliary trigger lines [3,4], the NA62 physics program includes most of the + decay channels and the possibility of precisely measuring decays as + → 0 + , + → + + + and + → + . ( 3 ) decay is defined as as subset of the inclusive decays + → 0 + ( ) ( 3 ) defined by requiring a minimum value of the energy of the radiative photon and a range of angles between the photon and the positron in the Kaon rest frame.…”
