The anomalous $$U(1)_{\mathrm{anom}}$$ U ( 1 ) anom symmetry and flavors from an SU(5) $$\times $$ × SU(5) $$'$$ ′ GUT in $$\mathbf{Z}_{12-I}$$ Z 12 - I orbifold compactification
Abstract In string compactifications, frequently the anomalous U(1) gauge symmetry appears which belongs to $$E_8 \times E_8'$$ E 8 × E 8 ′ of the heterotic string. This anomalous U(1) gauge boson obtains mass at the compactification scale ( $$\approx 10^{18\,}\,\text {GeV}$$ ≈ 10 18 GeV ) by a...
