The pentaquark in K-plus-d total cross section data

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 $0.9\pm 0.3$ MeV and the mass is $1.559\pm 0.003$ GeV/c${}^2$ for spin-parity $\h^+$ and $1.547\pm 0.002$\ GeV/c${}^2$ for $\h^-$. The errors are one standard deviation and statistical only. \
