String MSSM through flipped SU(5) from Z_{12} orbifold

Abstract

In a $Z_{12-I}$ orbifold compactification through an intermediate flipped SU(5), the string MSSM ($\mathcal{S}$MSSM) spectra (three families, one pair of Higgs doublets, and neutral singlets) are obtained with the Yukawa coupling structure. The GUT ${\sin }^2{\theta }_W^0=\frac{3}{8}$, even with exotics in the twisted sector, can be run to the observed electroweak scale value by mass parameters of vectorlike exotics near the GUT scale. We also obtain R-parity and doublet-triplet splitting.
