DESCRIPTION:A class of hidden sector polystable vector bundles will be pre
 sented that\, when used in combination with SU(4) heterotic standard model
  bundles\, lead to completely stable string vacua with exactly the particl
 e spectrum of the MSSM with three right-handed neutrino supermultiplets. T
 hreshold corrections\, the effective Lagrangian with soft supersymmetry br
 eaking and its scaling under the renormalization group are discussed. It i
 s shown that gauged B-L symmetry and electroweak symmetry are radiatively 
 broken with a small hierarchy over a wide range of initial parameters. Imp
 lications of these SU(4) heterotic standard models for the LHC are explore
