Direct Search Implications for a Custodially-Embedded Composite Top
R. Sekhar Chivukula, Roshan Foadi, Dennis Foren +1
We assess current experimental constraints on the bi-doublet + singlet model of top compositeness previously proposed in the literature. This model extends the standard model's spe…
Effect of four-fermion operators on the mass of the composite particles
Roshan Foadi
We propose a theoretical framework for evaluating the effect of four-fermion operators on the mass of composite particles in confining strongly-coupled gauge theories. The confinin…
Dynamical Origin of the Electroweak Scale and the 125 GeV Scalar
Stefano Di Chiara, Roshan Foadi, Kimmo Tuominen +1
We consider a fully dynamical origin for the masses of weak gauge bosons and heavy quarks of the Standard Model. Electroweak symmetry breaking and the gauge boson masses arise from…
Custodial Vector Model
Diego Becciolini, Diogo Buarque Franzosi, Roshan Foadi +3
We analyze the Large Hadron Collider (LHC) phenomenology of heavy vector resonances with a spectral global symmetry. This symmetry partially protects the el…
125 GeV Higgs from a chiral-techniquark model
Stefano Di Chiara, Roshan Foadi, Kimmo Tuominen
We consider the spin-zero spectrum of a strongly coupled gauge theory. In particular, we focus on the dynamical mass of the isosinglet scalar resonance in the presence of a four-fe…
The unobservable axial-pion mixing in QCD and near-conformal dynamics
Roshan Foadi
We study a chiral quark model of , , , and mesons in the large- limit. We show that the quadratic mixing can be set to zero at zero momentum, thus prote…
