Searching singlet extensions of the supersymmetric standard model in $Z_{6−II}$ orbifold compactification of heterotic string
Abstract : We search for supersymmetric standard model realizations with extra singlets and extra U(1) using the heterotic string compactification on the $Z_{6−II}$ orbifold with two Wilson lines. The effective superpotential produced through the vacuum restabilization mechanism is examined for three representative Pati-Salam string models obtained in the literature. An automated selection of semirealistic vacua along flat directions in the non-Abelian singlet modes field space is performed by requiring the presence of massless pairs of electroweak Higgs bosons having trilinear superpotential couplings with massless singlet modes and the decoupling of color triplet exotic modes needed to suppress $B$ and $L$ number violating processes.
