Abstract
The final result on the charged kaon semileptonic form factors from the NA48/2 experiment is presented. The measurement is based on 4.28 million K±e3 and 2.91 million K±μ3 events collected in 2004 with very low background (<0:1% and ∼0:2%, respectively). The joint analysis of these samples provides the most precise combined measurement of K±l3 form factors.
