论文摘要
牢固地认为，解决强大CP问题的斧头必须来自异常的Peccei-Quinn全球对称性的自发破坏。在这里，我们表明了一种新的可能性，即轴可以由伪金石seesaw机制诱导，尽管完全禁止使用Peccei-Quinn对称性。具体而言，在自发断裂适当的仪表和离散对称性之后，允许将重型伪金石耦合到彩色费米子与超轻伪金石结合在一起。在我们的情况下，不需要在TEV量表之上进行对称破裂。这意味着丰富的对撞机现象探索轴心的起源。
It is firmly believed that the axion for solving the strong CP problem must come from the spontaneous breaking of an anomalous Peccei-Quinn global symmetry. Here we show a new possibility that the axion can be induced by a pseudo Goldstone seesaw mechanism although the Peccei-Quinn symmetry is exactly forbidden. Specifically, after the spontaneous breaking of appropriate gauge and discrete symmetries, a heavy pseudo Goldstone coupling to colored fermions is allowed to have a tiny mass mixing with an ultralight pseudo Goldstone. In our scenario, no symmetry breaking is required to happen above the TeV scale. This means rich collider phenomena to explore the origin of axion.
