Viability of light-Higgs strongly-coupled scenarios
Juan Jose Sanz-Cillero, Antonio Pich, Ignasi Rosell
Contrary to what is sometimes stated, the current electroweak precision data easily allow for massive composite resonance states at the natural EW scale, i.e., well over the TeV. T…
Towards a general analysis of LHC data within two-Higgs-doublet models
Alejandro Celis, Victor Ilisie, Antonio Pich
The data accumulated so far confirm the Higgs-like nature of the new boson discovered at the LHC. The Standard Model Higgs hypothesis is compatible with the collider results and no…
Precision Tau Physics
Antonio Pich
Precise measurements of the lepton properties provide stringent tests of the Standard Model and accurate determinations of its parameters. We overview the present status of tau phy…
Oblique S and T Constraints on Electroweak Strongly-Coupled Models with a Light Higgs
Antonio Pich, Ignasi Rosell, Juan Jose Sanz-Cillero
Using a general effective Lagrangian implementing the chiral symmetry breaking SU(2)L x SU(2)R -> SU(2){L+R}, we present a one-loop calculation of the oblique S and T parameters wi…
Electric Dipole Moments in Two-Higgs-Doublet Models
Martin Jung, Antonio Pich
Electric dipole moments are extremely sensitive probes for additional sources of CP violation in new physics models. Specifically, they have been argued in the past to exclude new…
The Physics of the Higgs-like Boson
Antonio Pich
The present knowledge on the Higgs-like boson discovered at the LHC is summarized. The data accumulated so far are consistent with the Standard Model predictions and put interestin…
Strongly Coupled Models with a Higgs-like Boson
Antonio Pich, Ignasi Rosell, Juan Jose Sanz-Cillero
Considering the one-loop calculation of the oblique S and T parameters, we have presented a study of the viability of strongly-coupled scenarios of electroweak symmetry breaking wi…
Review of alpha_s determinations
Antonio Pich
The present knowledge on the strong coupling is briefly summarized. The most precise determinations of alpha_s, at different energies, are reviewed and compared at the Z mass scale…
B -> D(*) Tau Nu decays in two-Higgs-doublet models
Alejandro Celis, Martin Jung, Xin-Qiang Li +1
A sizable excess with respect to the SM expectation has been reported recently by the BaBar collaboration in the decay rates B -> D(*) Tau Nu, normalized by the corresponding light…
LHC constraints on two-Higgs doublet models
Alejandro Celis, Victor Ilisie, Antonio Pich
A new Higgs-like boson with mass around 126 GeV has recently been discovered at the LHC. The available data on this new particle is analyzed within the context of two-Higgs doublet…
