Semi-perturbative unification with extra vector-like families
We make a comprehensive analysis of an extended supersymmetric model(ESSM) obtained by adding a pair of vector-like families to the minimal supersymmetric standard model and having specific forms of 5×5 fermion mass matrices. The singlet Higgs couplings which link the ordinary to vector-like generations do not have the renormalization effects of the gauge interactions and hence the “quasi-infra...

We make a comprehensive analysis of an extended supersymmetric model (ESSM) obtained by adding a pair of vector-like families to the minimal supersymmetric standard model and having specific forms of 5 × 5 fermion mass matrices. The two-loop Yukawa effects lead to an unified coupling ∼ 0.2 and unification scale ∼ 1016.9 GeV. The renormalization effects of the extra vectorlike generations on sof...
متن کاملLow-Energy Signatures of Semi-perturbative Unification
We consider the low-energy signatures of, and high-energy motivations for, scenarios of semi-perturbative gauge coupling unification. Such scenarios can leave striking imprints on the low-energy sparticle spectrum, including novel gaugino mass ratios (including M2/M1 ≈ 1), substantial compression of the intra-generational squark-to-slepton mass ratios, and an overall lifting of scalar masses re...
متن کاملThree loop soft running , benchmark points and semi - perturbative unification
We consider three-loop β-function corrections to the sparticle spectrum in the MSSM, with particular emphasis on Snowmass Benchmark points. The three loop running has little effect on the weakly interacting particle spectrum, but for the squark masses the effect can be comparable to, or greater than, that of two loop running. We extend the analysis to the semi-perturbative unification scenario,...
متن کاملPower-Like Threshold Corrections to Gauge Unification in Extra Dimensions
One of the much-debated novel features of theories with extra dimensions is the presence of power-like loop corrections to gauge coupling unification, which have the potential of allowing a significant reduction of the unification scale. A recognized problem of such scenarios is the UV sensitivity of the above power corrections. We consider situations where the grand unified group is broken by ...
