Description

We introduce and investigate the effects of a light scalar interacting with the
short-lived kaon and the $K_S → μ^+μ^−$ decay. We use the results of searches performed at
kaon factories as well as the Standard Model predictions for this decay to constrain the
couplings of a ϕ particle with a mass $m_ϕ$ of the order of MeV. We also examine the time evolution of the kaon beams with the full mixing considered and the effect of its lifetime on extractable experimental parameters.
