Finite-size scaling for four-dimensional Higgs-Yukawa model near the Gaussian fixed point
• Mathematics, Physics
Journal of High Energy Physics
• 2019
A bstractWe analyse finite-size scaling behaviour of a four-dimensional Higgs-Yukawa model near the Gaussian infrared fixed point. Through improving the mean-field scaling laws by solving one-loop
Electroweak Constraints on the Fourth Generation at Two Loop Order
If the Higgs-like particle at 126 GeV is the standard model Higgs boson, then SM4, the simplest four generation extension of the SM, is inconsistent with the most recent LHC data. However, 4G
FOURTH GENERATION MAJORANA NEUTRINO, DARK MATTER AND HIGGS PHYSICS
• Physics
• 2014
We consider extensions of the standard model with fourth generation fermions (SM4) in which extra symmetries are introduced such that the transitions between the fourth generation fermions and the
Bootstrap Dynamical Symmetry Breaking
Despite the emergence of a 125 GeV Higgs-like particle at the LHC, we explore the possibility of dynamical electroweak symmetry breaking by strong Yukawa coupling of very heavy new chiral quarks .
Conformal completion of the standard model with a fourth generation
• Physics
• 2012
A bstractWe study dynamical electroweak symmetry breaking with a fourth generation within the Zn orbifolded AdS5 ⊗ S5 framework. A realistic Z7 example is discussed. The initial theory reduces

The Strongly Coupled Fourth Family and a First-Order Electroweak Phase Transition. I
• Physics
• 2009
In models of dynamical electroweak symmetry breaking due to strongly coupled fourthfamily quarks and leptons, their low-energy effective descriptions may involve multiple composite Higgs fields,
Extra families, Higgs spectrum, and oblique corrections
• Physics
• 2001
The standard model accommodates, but does not explain, three families of leptons and quarks, while various extensions suggest extra matter families. The oblique corrections from extra chiral families
Four generations and Higgs physics

In the light of the LHC, we revisit the implications of a fourth generation of chiral matter. We identify a specific ensemble of particle masses and mixings that are in agreement with all current
Minimal SU(5) Resuscitated by Higgs Coupling Fixed Points
The issue of gauge unification in the (non-supersymmetric) Standard Model is reinvestigated. It is found that with just an additional fourth generation of quarks and leptons, \$SU(3) \otimes SU(2)

It is found that the constraint on mass splitting which now also depends on the Higgs boson mass gives rise to some interesting phenomena, including the possibility of having a top-quark mass greater than 180 GeV.
Electroweak phase transition in the minimal supersymmetric standard model with four generations
• Physics

By assuming the existence of the sequential fourth generation to the minimal supersymmetric standard model (MSSM), we study the possibility of a strongly first-order electroweak phase transition. We
