“proton decay”的概念、定义、习题解题方法及翻译-物理辞典

单词	proton decay
释义	proton decay A process of the type p → e⁺ + π⁰ where a proton decays into a positron and a pion, predicted to occur in grand unified theories (GUTs) because baryon number is no longer conserved. The lifetime depends on the theory used and is typically 10³⁵ years, but a combination of GUTs and supersymmetry gives a lifetime of about 10⁴⁵ years. Considerable experimental effort has been spent in looking for proton decay, so far with no success
