Spontaneous proton decay and the origin of Peccei–Quinn symmetry
We propose a new interpretation of Peccei–Quinn symmetry within the Standard Model, identifying it with the axial B+L symmetry i.e. U(1)PQ≡U(1)γ5(B+L). This new interpretation retains all the attractive features of Peccei–Quinn solution to strong CP problem but in addition also leads to several othe...
