摘要:

我们提出了一个新的时间投影室粒子探测器(TPC),以寻找弱相互作用玻色子的存在,并调查的X17玻色子的存在,提出了由ATOMKI组解释的异常结果中产生的电子-正电子对的角分布质子诱导的核反应。我们的设计将提供比ATOMKI高200倍的灵敏度,研究计划还将在5 - 25 MeV的质量范围内提供世界领先的弱相互作用玻色子限制。

英文摘要:

We propose a new Time Projection Chamber particle detector (TPC) to search for the existence of feebly-interacting bosons and to investigate the existence of the X17 boson, proposed by the ATOMKI group to explain anomalous results in the angular distributions of electron-positron pairs created in proton-induced nuclear reactions. Our design will provide 200 times greater sensitivity than ATOMKI and the program of research will also provide world-leading limits on feebly interacting bosons in the mass range of 5 - 25 MeV.
