First Simultaneous K${}^{-}$p $\to ({\mathrm{\Sigma }}^0\mathrm{/}\mathrm{\Lambda }){\pi }^0$ Cross Sections Measurements at 98 MeV/c

We report the first simultaneous and independent measurements of the K${}^{-}$p $\to {\mathrm{\Sigma }}^0{\pi }^0$ and K${}^{-}$p $\to \mathrm{\Lambda }{\pi }^0$ cross sections around 100 MeV/c kaon momentum. The kaon beam delivered by the DA$\mathrm{\Phi }$NE collider was exploited to detect K${}^{-}$ absorptions on Hydrogen atoms, populating the gas mixture of the KLOE drift chamber. The precision of the measurements (${\sigma }_{K^{-}p\to {\mathrm{\Sigma }}^0{\pi }^0}=42.8\pm 1.5(stat\mathrm{.}{)}_{-2.0}^{+2.4}(syst\mathrm{.})\mathrm{m}\mathrm{b}$ and ${\sigma }_{K^{-}p\to \mathrm{\Lambda }{\pi }^0}=31.0\pm 0.5(stat\mathrm{.}{)}_{-1.2}^{+1.2}(syst\mathrm{.})\mathrm{m}\mathrm{b}$) is the highest yet obtained in the low kaon momentum regime.
