Abstract

This Letter reports on a new high precision measurement of the form factors of the K_L → π^± μ^∓ ν_μ decay. The data sample of about 2.3 × 10⁶ events was recorded in 1999 by the NA48 experiment at CERN. Studying the Dalitz plot density we measured a linear, λ₊^′ = (20.5 ± 2.2_stat ± 2.4_syst) × 10^-3, and a quadratic, λ₊^″ = (2.6 ± 0.9_stat ± 1.0_syst) × 10^-3 term in the power expansion of the vector form factor. No evidence was found for a second order term for the scalar form factor; the linear slope was determined to be λ₀ = (9.5 ± 1.1_stat ± 0.8_syst) × 10^-3. Using a linear fit our results were: λ₊ = (26.7 ± 0.6_stat ± 0.8_syst) × 10^-3 and λ₀ = (11.7 ± 0.7_stat ± 1.0_syst) × 10^-3. A pole fit of the form factors yields: m_V = (905 ± 9_stat ± 17_syst) MeV / c² and m_S = (1400 ± 46_stat ± 53_syst) MeV / c².

The data sample of about 2.3 × 106 events was recorded in 1999 by the NA48 experiment at CERN.
