Abstract |
We show that when an anomalous and a non-anomalous global symmetries are spontaneously and simultaneously broken, the resulting Nambu-Goldstone boson is associated with the non-anomalous one. Applied to the Majoron, this implies that its underlying symmetry is B-L rather than L, naturally resolving the domain wall problem. This result further demonstrates that effective couplings of the form a F F do not uniquely indicate an anomalous origin, allowing the detection of non-anomalous Nambu-Goldstone bosons in searches for axion-gauge boson interactions. |
