Abstract:

We show realistic supersymmetric standard-like models from SO(32) heterotic string theory on factorizable tori and smooth, quotient complete intersection Calabi-Yau three-folds with multiple line bundles. The stable line bundles lead to the three chiral generations of quarks and leptons without chiral exotics. Massless spectra of our models also include Higgs fields, which have desired Yukawa couplings to quarks and leptons at the tree-level. Finally, we discuss the axion-induced baryogenesis scenario induced by the axion-dependent Yukawa couplings.
