The pentaquark in K-plus-d total cross section data
W. R. Gibbs
Abstract
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 + and 1.5470.002\ GeV/c2 for -. The errors are one standard deviation and statistical only. \
