High-resolution spectrometer measurements of the reaction H(e,e′K+)X at small Q2 are used to extract the mass and width of the Λ(1520). We investigate dependence of the resonance parameters on different parametrizations of the background and the resonance peak itself. Our final values for the Breit-Wigner parameters are M=1520.4±0.6(stat.)±1.5(syst.)MeV and Γ=18.6±1. 9(stat.)±1(syst.)MeV. The width appears to be more sensitive to the assumptions than the mass. We also estimate, for the first time, the pole position for this resonance and find that both the pole mass and width seem to be smaller than their Breit-Wigner values. © 2011 American Institute of Physics.
