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
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
Two Higgs doublets, a 4th generation and a 125 GeV Higgs: a review
• Physics
• 2012
We review the possible role that multi-Higgs models may play in our understanding of the dynamics of a heavy 4th sequential generation of fermions. We describe the underlying ingredients of such
Lorentz Violation by Quark Condensation
At the TeV scale, heavy quarks, for example the 4th generation quarks of the Standard Model with four generations, can form condensates which dynamically break the electroweak symmetry. A dense quark

Towards an asymptotic-safety scenario for chiral Yukawa systems

AbstractWe search for asymptotic safety in a Yukawa system with a chiral U(NL)L  ⊗ U(1)R symmetry, serving as a toy model for the standard-model Higgs sector. Using the functional RG as a

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
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
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 proposed that a dynamical mass for a fourth family of quarks is responsible for breaking of the weak interactions, and for breaking of the extended-technicolor interactions which provide mass

A dynamical generalization of the seesaw mechanism is proposed based upon the BCS theory in which a neutrino condensate gives rise to right-handed-neutrino Majorana masses and all associated spin-zero bosons are composite.
The Discovery of the fourth family at the LHC: What if?
The first evidence of new strong interactions may be a sufficiently massive fourth family observed at the LHC. The fourth family masses, of the leptons in particular, are constrained by the
