Higgs Compositeness from Top Dynamics and Extra Dimensions
نویسنده
چکیده
The fundamental Higgs doublet may be replaced in the Standard Model by certain nonperturbative four-quark interactions, whose e ect is to induce a composite Higgs sector responsible for electroweak symmetry breaking. A simple composite two-Higgs-doublet model is presented. The four-quark interactions arise naturally if there are either extra spatial dimensions or larger gauge symmetries at a multi-TeV scale. Some theoretical and phenomenological implications of these scenarios are discussed.

DØ Note 5733-CONF First Measurement of Dijet Angular Distributions in the TeV Regime and Searches for Quark Compositeness and Extra Dimensions
We present a measurement of dijet angular distributions in Run II of the Fermilab Tevatron collider. The measurement is based on the Run IIa dataset, corresponding to an integrated luminosity of ≈ 0.7 fb taken with the DØ detector. Normalized shapes of dijet angular distributions have been measured over a range of dijet masses, from 0.25 TeV to above 1.1TeV. This is the first time in collider-b...
متن کاملUniversal Extra Dimensions and b → sγ
We analyze the effect of flat universal extra dimensions (i.e., extra dimensions accessible to all SM fields) on the process b → sγ. With one Higgs doublet, the dominant contribution at one-loop is from Kaluza-Klein (KK) states of the charged would-be-Goldstone boson (WGB) and of the top quark. The resulting constraint on the size of the extra dimension is comparable to the constraint from T pa...
متن کاملGravity-mediated (or composite) dark matter
Dark matter could have an electroweak origin, yet it could communicate with the visible sector exclusively through gravitational interactions. In a setup addressing the hierarchy problem, we propose a new dark-matter scenario where gravitational mediators, arising from the compactification of extra dimensions, are responsible for dark-matter interactions and its relic abundance in the Universe....
متن کاملCompositeness Condition and Vacuum Stability
We consider what occurs when we remove one of the compositeness conditions proposed by Bardeen, Hill and Lindner that leads to predictions for the top quark mass conflicting with the experimental value. Through this consideration the condition for the Higgs particle to be the composite particle is reconsidered. We show that in this case, (I) the Higgs-Yukawa system of the standard model becomes...
متن کاملPartially composite 2-Higgs doublet model
In the extra dimensional scenarios with gauge fields in the bulk, the KaluzaKlein (KK) gauge bosons can induce Nambu-Jona-Lasinio (NJL) type attractive fourfermion interactions, which can break electroweak symmetry dynamically with accompanying composite Higgs fields. We consider a possibility that electroweak symmetry breaking (EWSB) is triggered by both a fundamental Higgs and a composite Hig...
