Description
An analysis of K+-d total cross section data is undertaken to explore possible effects of the recently observed resonance in the S=+1 hadronic system with mass around 1.55 GeV. It is found that a structure corresponding to the resonance is visible in the data. The width consistent with the observed deviation from background is found to be 0.9±0.3 MeV and the mass is 1.559±0.003 GeV/c2 for spin parity (1/2)+ and 1.547±0.002 GeV/c2 for (1/2)-. The errors are one standard deviation and statistical only
