有人认为,解决强CP问题所需的Peccei-QuinnU(1)PQ对称性和弱相互作用的局域B-L对称性可能在相同的大质量尺度下被打破,导致大质量(但轻)中微子和非常轻的轴子。我们确定在anSO(10)模型的背景下,这个质量标度在109-1015 GeV之间,取决于sin 2 θw的值。这将超轻轴子的可能可见性与小中微子质量的可观测性联系起来。
It is argued that the Peccei—QuinnU(1)PQ symmetry, needed to solve the strong CP-problem, and the localB−L symmetry of weak interactions may be broken at the same large mass scale leading to massive (but light) neutrinos and a very light axion. We determine this mass scale in the context of anSO (10) model to be between 109–1015 GeV, depending on the value of sin2θw. This links the possible visibility of the superlight axion to the observability of the small neutrino mass.
