Neutrinos and Lepton Flavour Violation in the Left-Right Twin Higgs Model
Asmaa Abada, Irene Hidalgo
We analyse the lepton sector of the Left-Right Twin Higgs Model. This model offers an alternative way to solve the "little hierarchy" problem of the Standard Model. We show that on…
Expectations for LHC from Naturalness: Modified vs. SM Higgs Sector
J. A. Casas, J. R. Espinosa, I. Hidalgo
Common lore has it that naturalness of electroweak breaking in the SM requires new physics (NP) at Lambda < 2-3 TeV, hopefully within the reach of LHC. Moreover the Higgs should be…
The Fine-Tuning Problem in Little Higgs Models
Irene Hidalgo
Little Higgs models represent an alternative to Supersymmetry as a solution to the Hierarchy Problem. After introducing the main physical ideas of these models, we present the fine…
Implications for New Physics from Fine-Tuning Arguments: II. Little Higgs Models
J. A. Casas, J. R. Espinosa, I. Hidalgo
We examine the fine-tuning associated to electroweak breaking in Little Higgs scenarios and find it to be always substantial and, generically, much higher than suggested by the rou…
Implications for New Physics from Fine-Tuning Arguments: I. Application to SUSY and Seesaw Cases
J. A. Casas, J. R. Espinosa, I. Hidalgo
We revisit the standard argument to estimate the scale of new physics (NP) beyond the SM, based on the sensitivity of the Higgs mass to quadratic divergences. Although this argumen…
A Relief to the Supersymmetric Fine Tuning Problem
J. A. Casas, J. R. Espinosa, I. Hidalgo
As is well known, electroweak breaking in the MSSM requires substantial fine-tuning. We explain why this fine tuning problem is abnormally acute, and this allows to envisage possib…
