Flat Tree-level Inflationary Potentials in Light of CMB and LSS Data
G. Ballesteros, J. A. Casas, J. R. Espinosa +2
We use cosmic microwave background and large scale structure data to test a broad and physically well-motivated class of inflationary models: those with flat tree-level potentials…
Cosmological implications of the Higgs mass measurement
J. R. Espinosa, G. Giudice, A. Riotto
We assume the validity of the Standard Model up to an arbitrary high-energy scale and discuss what information on the early stages of the Universe can be extracted from a measureme…
Unparticles-Higgs Interplay
Antonio Delgado, Jose R. Espinosa, Mariano Quiros
We show that scalar unparticles coupled to the Standard Model Higgs at the renormalizable level can have a dramatic impact in the breaking of the electroweak symmetry already at tr…
Neutrino Masses in the Lee-Wick Standard Model
Jose Ramon Espinosa, Benjamin Grinstein, Donal O'Connell +1
Recently, an extension of the standard model based on ideas of Lee and Wick has been discussed. This theory is free of quadratic divergences and hence has a Higgs mass that is stab…
Novel Effects in Electroweak Breaking from a Hidden Sector
Jose Ramon Espinosa, Mariano Quiros
The Higgs boson offers a unique window to hidden sector fields S_i, singlets under the Standard Model gauge group, via the renormalizable interactions |H|^2 S_i^2. We prove that su…
