K+ semileptonic decay form factor study in the Γ(Kμ3)/Γ(Ke3) measurement
Description
The ratio of the K+ → π0μ+ν (Kμ3+) and K+ → π0e+ν (Ke3+) decay widths, Γ(Kμ3)/Γ(Ke3), has been measured. Calculating the detector acceptance by a Monte Carlo simulation, the Γ(Kμ3)/Γ(Ke3) ratio was obtained to be 0.671±0.007(stat.)±0.008(syst.). The coefficient of the q2 dependent term of the f0 form factor was also determined to be λ0=0.022±0.005(stat.)±0.004(syst.). (author)
