摘要：This paper is devoted to the measurement of the fully inclusive of photon radiation absolute
branching ratios of the semileptonic charged-kaon decays, K± ! p0e±n (g ) and K± !
p0m±n (g ). The measurements have been done using a tag technique, via identification of the twobody
decays K±!m±n and K±!p±p0, and using a sample of about 410 pb−1 collected during
the 2001 and 2002 data taking of the KLOE experiment at DAFNE, the Frascati f factory . The
results obtained are BR(Ke3) = 0.04965 (38)Stat (37)Syst and BR(Km3) = 0.03233 (29)Stat (26)Syst .
