搜索ppK -在GSI进行质子诱导反应

Search for ppK- with proton induced reactions at GSI

L. Fabbietti

摘要:

为了研究深束缚K介子态的存在性,进行了几个K介子束实验。我们提出了另一种方法,利用3.5GeV入射能量的p+p反应来搜索最基本的K介子态:ppK-。该实验计划使用GSI的FOPI光谱仪进行,并开发了一种硅基触发系统,以提高现有系统对感兴趣反应的检测能力。在真实的光束条件下进行了几次测试,以测试测量的可行性和触发系统原理的证明。这种测量的积极结果与从模拟中提取的预期比率一起显示在本文中。

英文摘要:

Several experiments engaging kaon beams have been carried out to study the existence of deeply bound kaonic state. We proposed an alternative method, which exploits a p+p reaction at 3.5GeV incoming energy to search for the most elementary of the kaonic states: ppK-. This experiment is planned with the FOPI spectrometer at GSI and a silicon-based trigger system has been developed to increase the detection capability of the existing system for the reaction of interest. Several tests have been performed under realistic beam conditions to test the feasibility of the measurement and the proof of principle of the trigger system. The positive results of such measurements are shown in this contribution together with the expected rates extracted from simulations.
