Abstract

Recently, a group directed by A. J. Krasznahorkay observed an anomaly in the emission of electron–positron pairs in three different nuclear reactions, namely, the 3H(p,e−e+)4He, 7Li(p,e−e+)8Be, and 11B(p,e−e+)12C processes. Kinematics indicate that this anomaly might be due to the de-excitation of 4He, 8Be, and 12C nuclei with the emission of a boson with a mass of about 17 MeV, rapidly decaying into e−e+ pairs. The result of the experiments performed with the singletron accelerator of ATOMKI is reviewed, and the consequences of the so-called X17 boson in particle physics and in cosmology are discussed. Forthcoming experiments designed to shed light on the possible existence of the X17 boson are also reported.
X17:现状与展望
最近,由 A. J. Krasznahorkay 指导的一个研究小组在三种不同的核反应(即 3H(p,e-e+)4He、7Li(p,e-e+)8Be 和 11B(p,e-e+)12C)过程中观察到了电子-正电子对发射的异常现象。运动学表明,这种异常可能是由于 4He、8Be 和 12C 核的去唤起,发射出质量约为 17 MeV 的玻色子,迅速衰变为 e-e+ 对。本文回顾了利用 ATOMKI 单子加速器进行的实验结果,并讨论了所谓的 X17 玻色子在粒子物理学和宇宙学中的影响。还报告了即将进行的旨在揭示 X17 玻色子可能存在的实验。
