Abstract
- The NA48/2 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2003-2004. An upper limit of $8.6 \times 10^{-11}$ at 90~$\%$~CL is set on the branching ratio of the lepton number violating decay $K^\pm \rightarrow \pi^{\mp} \mu^{\pm} \mu^{\pm}$. Searches for two-body resonances like heavy neutral leptons and inflatons in the $K^\pm \rightarrow \pi \mu \mu$ decays in the accessible range of masses and lifetimes are also presented.
