$SU(2)$ gauge theory with two fundamental flavours: scalar and pseudoscalar spectrum [PDF]

, 2016
We investigate the scalar and pseudoscalar spectrum of the $SU(2)$ gauge theory with $N_f=2$ flavours of fermions in the fundamental representation using non perturbative lattice simulations.

Constraining composite Higgs models using LHC data

Journal of High Energy Physics, 2018
We systematically study the modifications in the couplings of the Higgs boson, when identified as a pseudo Nambu-Goldstone boson of a strong sector, in the light of LHC Run 1 and Run 2 data.

Composite (Goldstone) Higgs Dynamics on the Lattice: Spectrum of SU(2) Gauge Theory with two Fundamental Fermions [PDF]

, 2014
We study the meson spectrum of the SU(2) gauge theory with two Wilson fermions in the fundamental representation. The theory unifies both Technicolor and composite Goldstone Boson Higgs models of electroweak symmetry breaking.

Light composite Higgs boson from the normalized Bethe-Salpeter equation

, 2009
Scalar composite boson masses have been computed in QCD and technicolor theories with the help of the homogeneous Bethe-Salpeter equation, resulting in a scalar mass that is twice the dynamically generated fermion or technifermion mass (m(dyn)).

Aspects of dynamical electroweak symmetry breaking

, 1990
In technicolor models it has recently been suggested that dynamics at scales much higher than the electroweak scale can play a significant role in electroweak symmetry breaking, and that these effects can lead to a heavy top quark while alleviating the ...

Higgs and collider phenomenology of physics beyond the standard model

, 2013
This thesis explores three classes of beyond-the-Standard Model (BSM) theories: Minimal Universal Extra Dimensions (MUED), the 4D Composite Higgs Model (4DCHM) and Technicolor.

Search for Pair Production of Leptoquarks in the CMS Experiment

, 2011
Leptoquarks are hypothetical particles carrying both lepton and quark flavor. They are predicted by Grand Unified Theories, technicolor and composite models, among others.

125 GeV scalar boson and SU(NTC)⊗ - SU(3) L⊗ - U(1)X models

, 2013
We verify that SU(N)TC⊗ - SU(3) L⊗ - U(1)X models, where the gauge symmetry breaking is totally dynamical and promoted by the non-Abelian technicolor group and the strong Abelian interactions, are quite constrained by the LHC data.
