The decay K[sup –] → μ[sup –]νπ[sup 0] has been studied using in-flight decays detected with the ISTRA+ setup operating in the 25-GeV negative secondary beam of the U-70 PS. About 112K events were used for the analysis. The λ[sub +] and λ[sub 0] slope parameters of the decay form factors f[sub +](t) and f[sub 0](t) have been measured: λ[sub +] = 0.0321 ± 0.004(stat.) ± 0.002(syst.), λ[sub 0] = 0.0209 ± 0.004(stat.) ± 0.002(syst.); the correlation dλ[sub 0]/dλ[sub +] = –0.46. The limits on the possible tensor and scalar couplings have been derived: f[sub T]/f[sub +](0) = –0.021 ± 0.028(stat.) ± 0.014(theor.), f[sub S]/f[sub +](0) = 0.004 ± 0.005(stat.) ± 0.005(theor.).© 2003 MAIK “Nauka / Interperiodica”.
