We present a measurement of the charged kaon semileptonic form factors based on 4.3 million K± ? p0e±?e and 2.9 million K± ? p0µ±?µ decays collected by the NA48/2 experiment. The single results for the semi-electronic and semi-muonic channel have better and similar precision, respectively, than previous measurements. The combination of both channels yields the most precise measurement of the form factors of semileptonic kaon decays.

Abstract
We present a measurement of the charged kaon semileptonic form factors based on 4.3 million K± ? p0e±?e and 2.9 million K± ? p0µ±?µ decays collected by the NA48/2 experiment. The single results for the semi-electronic and semi-muonic channel have better and similar precision, respectively, than previous measurements. The combination of both channels yields the most precise measurement of the form factors of semileptonic kaon decays.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
