Hypercharged naturalness

Journal of High Energy Physics, 2019
We present an exceptional twin-Higgs model with the minimal symmetry structure for an exact implementation of twin parity along with custodial symmetry.

Field theory as a tool to constrain new physics models

, 2015
One of the major problems in developing new physics scenarios is that very often the parameters can be adjusted such that in perturbation theory almost all experimental low-energy results can be accommodated.

Very light dilaton and naturally light Higgs boson

Journal of High Energy Physics, 2018
We study very light dilaton, arising from a scale-invariant ultraviolet theory of the Higgs sector in the standard model of particle physics. Imposing the scale symmetry below the ultraviolet scale of the Higgs sector, we alleviate the fine-tuning ...

Schwinger-Dyson approach and its application to generate a light composite scalar

, 2016
We discuss the possibility of generating a light composite scalar boson, in a scenario that we may generically call Technicolor, or in any variation of a strongly interacting theory, where by light we mean a scalar composite mass about one order of ...

Minimal Super Technicolor [PDF]

, 2011
We introduce novel extensions of the Standard Model featuring a supersymmetric technicolor sector. First we consider N=4 Super Yang-Mills which breaks to N=1 via the electroweak (EW) interactions and coupling to the MSSM.

Constraining scalar resonances with top-quark pair production at the LHC

Journal of High Energy Physics, 2018
Constraints on models which predict resonant top-quark pair production at the LHC are provided via a reinterpretation of the Standard Model (SM) particle level measurement of the top-anti-top invariant mass distribution, m t t ¯ $$ m\left(t\overline{t ...

Distinguishing among Technicolor/Warped Scenarios in Dileptons [PDF]

, 2011
Models of dynamical electroweak symmetry breaking usually include new spin-1 resonances, whose couplings and masses have to satisfy electroweak precision tests.

Twin Higgs with exact Z 2

Journal of High Energy Physics, 2020
We present a novel mechanism for realistic electroweak symmetry breaking in Twin Higgs/neutral naturalness models where the Z 2 exchange symmetry can remain exactly unbroken.

Limit on the fermion masses in technicolor models [PDF]

, 2003
Recently it has been pointed out that no limits can be put on the scale of fermion mass generation $(M)$ in technicolor models, because the relation between the fermion masses $(m_f)$ and $M$ depends on the dimensionality of the interaction responsible ...

Naturalness sum rules and their collider tests

Journal of High Energy Physics, 2019
We present the most general sum rules reflecting the cancellation of ultraviolet divergences in the Higgs potential, which provide necessary conditions for any weakly-coupled extension of the Standard Model to be natural. There is a separate sum rule for
