Finite temperature field theory and phase transitions
We review different aspects of field theory at zero and finite temperature, related to the theory of phase transitions. We discuss different renormalization conditions for the effective potential at
Opening the window for electroweak baryogenesis
We perform an analysis of the behaviour of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops. We show that, in previously unexplored
Improved Higgs mass stability bound in the standard model and implications for supersymmetry
Abstract We re-examine the lower bound on the mass of the Higgs boson, Mh, from Standard Model vaccum stability including next-to-leading-log radiative corrections. This amounts to work with the full
Analytical expressions for radiatively corrected Higgs masses and couplings in the MSSM
We propose, for the computation of the Higgs mass spectrum and couplings, a renormalization-group improved leading-log approximation, where the renormalization scale is fixed to the top-quark pole
Improved Results in Supersymmetric Electroweak Baryogenesis
Abstract Electroweak baryogenesis provides a very attractive scenario to explain the origin of the baryon asymmetry. The mechanism of electroweak baryogenesis makes use of the baryon number anomaly
Supersymmetric CP violating currents and electroweak baryogenesis
In this work we compute the CP-violating currents of the right-handed stops and higgsinos, induced by the presence of non-trivial vacuum expectation values of the Higgs fields within the context of
Bubbles in the supersymmetric standard model
Abstract We compute the tunneling probability from the symmetric phase to the true vacuum, in the first-order electroweak phase transition of the MSSM, and the corresponding Higgs profiles along the
Electroweak baryogenesis and new TeV fermions
Abstract New fermions, strongly coupled to the standard model Higgs boson, provide a well motivated extension of the standard model (SM). In this work we show that, once new physics at heavier scales
Soft masses in theories with supersymmetry breaking by TeV compactification
Abstract We study the sparticle spectroscopy and electroweak breaking of theories where supersymmetry is broken by compactification (Scherk-Schwarz mechanism) at a TeV The evolution of the soft terms
New ideas in symmetry breaking
Some old and new ideas on symmetry breaking, based on the presence of extra dimensions that have been the subject of a very fast development and intensive studies during the last years, will be
