论文摘要
在这篇研究论文中，我们研究了质子在具有圆极化的外部电磁场的情况下，质子衰减到中子，正电子和电子中微子。与这种衰减过程相关的不同物理量，例如质子的衰减率及其寿命，是根据S-矩阵方法计算的。质子和正电子被视为Dirac-Volkov状态，而中子和电子中微子是自由态。我们发现，尽管它不能在真空中发生，但在存在较高强度接近或接近Schwinger极限的激光场的存在下，质子的衰减过程将成为中子，正电子和电子中微子。此外，在此极限附近和某些频率上，质子的寿命可以与中子的寿命相媲美，而所需的激光强度（可能会导致这种衰减的所需的激光强度）取决于所选的激光源。
In this research paper, we investigate the decay of the proton into neutron, positron and electron neutrino in the presence of an external electromagnetic field with circular polarization. Different physical quantities related to this decay process, such as proton's decay rate and its lifetime, are calculated based on the S-matrix approach. The proton and positron are treated as Dirac-Volkov states, while the neutron and electron neutrino are free-states. We have found that, though it can not occur in vacuum, the proton's decay process into neutron, positron and electron neutrino becomes possible in the presence of laser field with high intensities near or close to the Schwinger limit. In addition, near this limit and for some frequencies, the proton's lifetime can be comparable to that of the neutron, and the required laser strength, from which this decay becomes possible, depends on the chosen laser source.
