Spectral action and the electroweak θ-terms for the Standard Model without fermion doubling
Spectral action and the electroweak θ-terms for the Standard Model without fermion doubling
We compute the leading terms of the spectral action for a noncommutative geometry model that has no fermion doubling. The spectral triple describing it, which is chiral and allows for CP-symmetry breaking, has the Dirac operator that is not of the product type. Using Wick rotation we derive explicitly the …
