Sažetak
We report the measurement of K^- absorption processes in the Sigma^0p final state and the first exclusive measurement of the two nucleon absorption (2NA) with the KLOE detector. The 2NA process without further interactions is found to be 9% of the sum of all other contributing processes, including absorption on three and more nucleons or 2NA followed by final state interactions with the residual nucleons. We also determine the possible contribution of the ppK^− bound state to the Sigma^0p final state. The yield ofppK^−/K^− stop is found to be (0.044 ± 0.009 stat^(+0.004)_(−0.005 syst)) · 10^(−2) but its statistical significance based on an F-test is only 1σ.
