    Description
The NA48/2 experiment at CERN collected in 2003-2004 a large sample of charged kaon decays with multiple charged particles in the final state.
A new upper limit on the rate of the lepton number violating decay K+-  -->  pi-+ mu+- mu+- obtained from this sample is reported. 
Searches for two-body resonances in the K+- -->pi mu mu decays (including heavy neutral leptons and inflatons) in the accessible 
range of masses and lifetimes are presented.
