论文摘要
确定两个稀有通道的质子，正电子和两个电子的杂物pSH的衰减速率，psh $ \ to p^+ e^ - γ$和psh $ \ to p^+ e^ - $。先前的研究分别按照约2和700的因素高估了这些速率。我们解释了这些错误预测的物理学。我们确认了一系列静态PSH性能，包括非相关基态能量，颗粒间距离及其功率的预期值，以及三个和四个粒子合并概率，使用高斯基础上的变异方法。
Decay rates of the positronium hydride PsH, a bound state of a proton, a positron, and two electrons, are determined for two rare channels, PsH $\to p^+ e^- γ$ and PsH $\to p^+ e^-$. Previous studies overestimated these rates by factors of about 2 and 700, respectively. We explain the physics underlying these wrong predictions. We confirm a range of static PsH properties, including the non-relativistic ground state energy, expectation values of inter-particle distances and their powers, and the three and four particle coalescence probabilities, using a variational method in the Gaussian basis.
