轻核中$K^-$静态吸收的相关$Λt$对

Correlated $Λt$ pairs from the absorption of $K^-$ at rest in light nuclei

M. Agnello

摘要:

本文报道了轻核$^{6,7}$ Li和$^{9}$ Be中$K^{-}_{stop}A$吸收反应的新数据。本研究旨在发现$Λt$相关性。不管$A$如何,$Λt$对优先在相反方向上发射。反应建模主要将$Λt$对的发射分配给$K^-_{stop}A\toΛt(N)A'$直接反应,发现其产率范围从$10^{-3}$到$10^{-4}$ $/K^-_{stop}$。实验使用DA $Φ$ NE(LNF)的FINUDA光谱仪进行。

英文摘要:

Novel data from the $K^{-}_{stop}A$ absorption reaction in light nuclei $^{6,7}$Li and $^{9}$Be are presented. The study aimed at finding $Λt$ correlations. Regardless of $A$, the $Λt$ pairs are preferentially emitted in opposite directions. Reaction modeling predominantly assigns to the $K^-_{stop}A\toΛt(N)A'$ direct reactions the emission of the $Λt$ pairs whose yield is found to range from $10^{-3}$ to $10^{-4}$$/K^-_{stop}$. The experiment was performed with the FINUDA spectrometer at DA$Φ$NE (LNF).
