The data collected by NA48/2 in 2003-2004 allowed several precise measurements in the charged kaon decay sector. In this paper we present the results obtained using a sample of 2.5×106 K± → π0μ±ν (Kμ3) and 4.0×106 K × → π0l ±ν (Ke3) events, collected in 2004 using a minimal trigger configuration.

Abstract
The data collected by NA48/2 in 2003-2004 allowed several precise measurements in the charged kaon decay sector. In this paper we present the results obtained using a sample of 2.5×106 K± → π0μ±ν (Kμ3) and 4.0×106 K × → π0l ±ν (Ke3) events, collected in 2004 using a minimal trigger configuration. This unbiassed sample of kaon decays allows a high precision measurement of the semileptonic form factors. © Copyright owned by the author(s).
