The pp -> K+Sigma(+)n cross-section from missing-mass spectra
The pp -> K+Sigma(+)n cross-section from missing-mass spectra
We utilize existing inclusive data on K+-meson momentum spectra of the reaction pp -> K+X at T-p = 2.3-2.85 GeV to deduce total cross-sections for pp -> K(+)Z(+)n. The method used to extract those 'cross-sections is explained and discussed in detail. Our result for T-p = 2.85 GeV is consi...

We utilize existing inclusive data on K+-meson momentum spectra of the reaction pp -> K+X at T-p = 2.3-2.85 GeV to deduce total cross-sections for pp -> K(+)Z(+)n. The method used to extract those 'cross-sections is explained and discussed in detail. Our result for T-p = 2.85 GeV is consistent with the data point from a direct measurement at the same beam energy. The cross-section obtained for T-p = 2.3 GeV is with 13.7 +/- 2.3pb considerably smaller than the value found in a recent experiment by the COSY-11 Collaboration at a somewhat lower beam energy, indicating that the pp -> K+Sigma(+)n, reaction cross-section could exhibit a rather unusual energy dependence. |
