Pentaquark in K+-d total cross section data -: art. no. 045208

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/c(2) for spin parity /12(+) and 1.547+/-0.002 GeV/c(2) for 1/2(-). The errors are one standard deviation and statistical only.
