Description

Rare Kaon meson decays serve as highly sensitive probes for both heavy and light New Physics. Notably, the $K_S\rightarrow\pi^+\pi^-\mu^+\mu^-$process, which is of order $10^{-14}$ in the Standard Model (SM), holds the potential to be enhanced by up to a factor of 100 in exotic Beyond the Standard Model (BSM) scenarios. The analysis of the $K_S\rightarrow\pi^+\pi^-\mu^+\mu^-$ decay is anticipated to exhibit high cleanliness owing to the exceptional performance of the LHCb experiment in pion and muon reconstruction. Results for $K_L\rightarrow\pi^+\pi^-\mu^+\mu^-$ will also be provided, for which there are no SM predictions. Herein, we present the current progress on the exploration of the $K_S\rightarrow\mu^+\mu^-\pi^+\pi^-$decay utilizing data from 2016-2018 of the LHCb experiment.
