dc.description.abstractWe calculate threshold corrections to the running gauge and Yukawa couplings in the cxceptional supersymmetric standard model (E⁶SSM) and analyze the more precise and reliable mass spectra in a constrained model (CE⁶SSM). Full expressions for the corrections are provided and the implementation into a spectrum generator is described. We find a dramatic reduction in the matching scale dependency of the masses of many states and observe a significant adjustment of the correlation of low-scale physical masses and high-scale parameters. Still, in substantial regions of parameter space the mass of the lightest Higgs is compatible with the new boson discovered at the LHC and the model satisfies limits from collider searches for squark, gluinos, and Z′ bosons. We study the implications for gauge coupling unification from a new dependency of the spectrum on so-called survival Higgs fields which cannot be addressed without the inclusion of the threshold corrections.
