标题： Pathways to proton's stability via naturally small neutrino masses

摘要： 在目前的工作中，我们研究了轻子质量小与质子稳定性之间的联系。 我们从不同的角度分析了这种联系：轻子质量的小和质子稳定性源自同一来源，轻子质量小导致长寿命的质子，以及质子衰变宽度的小作为自然小的轻子质量的原因。 所有方案都进行了详细的研究，并给出了UV实现。 我们讨论了每种方案的优点，并概述了进一步的研究方向。 显示英文摘要

摘要： In the present work, the connection between the smallness of the neutrino masses and the stability of the proton is studied. We analyze this connection from different perspectives: the smallness of neutrino mass and the proton stability originate from the same source, small neutrino masses lead to a long lived proton, and the smallness of the proton decay width as a cause of the naturally small neutrino masses. All the schemes are studied in detail and UV realizations are given. We discuss advantages of each scheme and outline further investigation directions.
