Question
Alternatives to the existence of these particles include some type of quark being massless, which is probably not true, and CP symmetry being spontaneously broken, which would lead to a complex Higgs VEV. For 10 points each:
[10m] Name these particles that are the Nambu–Goldstone bosons associated with spontaneous breaking of a theorized global U-one symmetry. The existence of these particles would resolve the strong CP problem.
ANSWER: axions
[10e] Peccei and Quinn’s original formulation incorrectly posited that the energy scale of U-one breaking was equal to that of the breaking of a symmetry in this interaction, a unification of two fundamental forces.
ANSWER: electroweak interaction [reject “electromagnetic interaction” or “weak interaction”]
[10h] The energy scale of U-one breaking is much larger than that of electroweak breaking in models described by this adjective, like the DFSZ and KSVZ models. Models described by this adjective admit axions light enough to agree with their lack of experimental observation.
ANSWER: invisible [accept invisible axion models or invisible axion theories]
