论文摘要

我们报告了K $^{ - } $ P $ \rightArrowσ^0 \,π^{0} $和k $^{ - } $ p $ p $ p $ p $ p $ p $ p $ p $ p $ p $ pugyλ\,π^{0} $交叉截面大约100 mev/c kaon Mompantum。 Da $φ$ ne对撞机传递的KAON光束被利用以检测氢原子上的K $^ - $吸收,从而填充了Kloe漂移室的气体混合物。测量值的精度($σ_{k^ - p \rightarrowσ^0π^0} = 42.8 \ pm 1.5(stat。)^{+2.4} _ { - 2.0}(syst。)(syst。) (stat。) ^{+1.2} _ { - 1.2}(syst。)\ \ mathrm {mb} \,$)是在低KAON动量制度中尚未获得的。

We report the first simultaneous and independent measurements of the K$^{-}$p $\rightarrow Σ^0 \, π^{0}$ and K$^{-}$p $\rightarrow Λ\, π^{0}$ cross sections around 100 MeV/c kaon momentum. The kaon beam delivered by the DA$Φ$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 ($σ_{K^- p \rightarrow Σ^0 π^0} = 42.8 \pm 1.5 (stat.) ^{+2.4}_{-2.0}(syst.) \ \mathrm{mb}$ and $σ_{K^- p \rightarrow Λπ^0} = 31.0 \pm 0.5 (stat.) ^{+1.2}_{-1.2}(syst.) \ \mathrm{mb}\,$) is the highest yet obtained in the low kaon momentum regime.
