We propose a novel mechanism to generate a collective quartic in composite Higgs models. We are inspired by the original little Higgs idea in which a tree level quartic arises from the dimensional reduction of 6-dimensional gauge theory. To connect to CH models, our model is set in warped 6D (AdS5xS1), deconstructed for simplicity into a two site 5D RS model. The size of the quartic is...

Non-QCD like confining gauge theories promise to be potential UV completions for the Standard Model Electroweak sector, which do not suffer from fine tuning problems. In these scenarios, the Higgs boson would be a composite particle that is kept lighter than other composites by the dynamics of the gauge theory. To determine the viability of this scenario, we have developed an...

In recent years, many numerical investigations of confining Yang Mills gauge theories near the edge of the conformal window

have been carried out using lattice gauge theory techniques. These studies have revealed that the spectrum of hadrons in nearly conformal gauge theories differs significantly from the QCD spectrum. In particular, a light singlet scalar appears
in the spectrum which is... -

Warped higher-dimensional compactifications with “bulk” standard model, or their AdS/CFT dual as the purely 4D scenario of Higgs compositeness and partial compositeness, offer an elegant approach to resolving the electroweak hierarchy problem as well as the origins of flavor structure. However, low-energy electroweak/flavor/CP constraints and the absence of non-standard physics at LHC suggest...

We proposed a natural generalization of standard Randall-Sundrum model, which can address both hierarchy problem and flavor problem, and also give interesting and new signals accessible at LHC. Kaluza-Klein gauge bosons in this model could have significant couplings to the corresponding SM gauge boson and radion. Radion has dominant decay channels to pairs of SM gauge bosons. The cascade...

Abstract: We study the collider signals in a recently proposed RS like scenario with 3 or more branes. This scenario can address both flavor and hierarchy problems and leads to new and interesting signals that are accessible at LHC. I will focus on the 3 brane case when the primary signal involves three EW gauge bosons in the final state. A robust feature of decays in this scenario is the...

In this talk, I discuss the early-universe cosmology of a Kaluza-Klein (KK) tower of scalar fields in the presence of a mass-generating phase transition. I focus on the time-development of the total tower energy density as well as its distribution across the different KK modes, and find that both of these features are extremely sensitive to the details of the phase transition and can behave...
