Spin-1 resonances
Stefania De Curtis, Daniele Dominici
Spin-1 resonances are naturally present in composite Higgs frameworks. We first review a model independent approach to parametrize a single additional heavy triplet and then we con…
Variational approach to thermal masses in compactified models
Daniele Dominici, Itzhak Roditi
We investigate by means of a variational approach the effective potential of a 5D U(1) scalar model at finite temperature and compactified on S^1 and S^1/Z_2 as well as the corresp…
Discovery and Mass Spectroscopy via Mixed Di-Boson Production at the LHC in a 4-Site Model with a Composite Higgs Boson
Stefania De Curtis, Daniele Dominici, Luca Fedeli +1
We investigate the scope of the Large Hadron Collider (LHC) in probing the parameter space of a 4-Site (4S) model supplemented by one composite Higgs state. We concentrate on the y…

E. Accomando, L. Fedeli, S. Moretti +2
We investigate the scope of the LHC in probing the parameter space of a 4-site model supplemented by one composite Higgs state, assuming all past, current and future energy and lum…
Indirect Sensitivity to Heavy Z' Bosons at a Multi-TeV e+e- Collider
Marco Battaglia, Francesco Coradeschi, Stefania De Curtis +1
We compare the phenomenology of two models, the so-called minimal Z' and an effective model for a SM-like Higgs realised as a composite state of a new strong interaction, at a mult…
Indirect sensitivity to Z's in high-energy e+e- collisions: a "standard" vs. "composite" study
Marco Battaglia, Francesco Coradeschi, Stefania De Curtis +1
We compare the phenomenology of two models, the so-called "minimal Z'" and an effective model an SM-like Higgs is realised as a composite state of a new strong interaction, at a mu…
Effective chiral Lagrangians for new vector bosons to O(p^4) order
Francesco Bernardini, Francesco Coradeschi, Daniele Dominici
If the SM Higgs boson does not exist, electroweak symmetry breaking may be realized via a strong interaction with a typical scale Lambda > 1 TeV. Resonances from the strong sector…
Interference effects in heavy W'-boson searches at the LHC
Elena Accomando, Diego Becciolini, Stefania De Curtis +3
Interference effects are widely neglected in searches for new physics. This is the case in recent publications on searches for W'-bosons using leptonic final states. We examine the…

Elena Accomando, Diego Becciolini, Stefania De Curtis +2
We study the phenomenology of the 4-site Higgsless model, based on the gauge symmetry, at present colliders. The model predicts t…
Improved analysis of the bounds from the electroweak precision tests on the 4-site model
Elena Accomando, Diego Becciolini, Stefania De Curtis +2
We present a new complete analysis of the electroweak precision observables within the recently proposed 4-site Higgsless model, which is based on the SU(2)_L x SU(2)_1 x SU(2)_2 x…
Z' production at the LHC in the four-site Higgsless model

We study the phenomenology of the neutral gauge sector of the four-site Higgsless model, based on the SU(2)_L x SU(2)_1 x SU(2)_2 x U(1)_Y gauge symmetry, at present colliders. The…
From hidden symmetry to extra dimensions: a five dimensional formulation of the Degenerate BESS model
Francesco Coradeschi, Stefania De Curtis, Daniele Dominici
We consider the continuum limit of a moose model corresponding to a generalization to N sites of the Degenerate BESS model. The five dimensional formulation emerging in this limit…

Daniele Dominici, John F. Gunion
We recompute the invisible Higgs decay width arising from Higgs-graviscalar mixing in the ADD model, comparing the original derivation in the non-diagonal mass basis to that in a d…
The four site Higgsless model at the LHC
E. Accomando, S. De Curtis, D. Dominici +1

CP Studies and Non-Standard Higgs Physics
S. Kraml, E. Accomando, A. G. Akeroyd +163
There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mi…

J. R. Pelaez, S. De Curtis, D. Dominici
Tree level unitarity violations of extra dimensional extensions of the Standard Model may become much stronger when the scalar sector is included in the bulk. This effect occurs wh…
