Abstract
The NA48/2 and NA62-RK experiments at CERN collected large samples of charged kaon decays in 2003–2004 and 2007, respectively. These samples, collected with different trigger conditions, allow to search for both short and long-living heavy neutrinos produced in K± → μ±N4 decays. The results of these complementary searches are presented in this paper. In the absence of observed signal, the limits obtained on B(K± → π∓μ±μ±), B(K± → μ±N4)B(N4 → πμ), B(K+ → μ+N4) and on the mixing matrix element |Uμ4| 2 are reported.
