A Unified View of Vacuum Decay Channels
J. R. Espinosa
The tunneling potential formalism, an alternative to the standard Coleman Euclidean approach, offers in a natural way a unified view of vacuum decays. In particular, I show in this…
The Unreasonable Effectiveness of the Tunneling Potential
J. R. Espinosa
The Tunneling Potential Formalism was introduced to calculate the tunneling actions that control vacuum decay as an alternative to the standard Euclidean Formalism. The new approac…
F-term inflation in Superstring Theories
J. A. Casas, G. B. Gelmini, A. Riotto
A supersymmetric inflationary stage dominated by an -term has the problem that the flatness of the potential is spoiled by supergravity corrections, that is the slow-roll parame…
Physics Implications of Flat Directions in Free Fermionic Superstring Models II: Renormalization Group Analysis
G. Cleaver, M. Cvetic, J. R. Espinosa +3
We continue the investigation of the physics implications of a class of flat directions for a prototype quasi-realistic free fermionic string model (CHL5), building upon the result…
Physics Implications of Flat Directions in Free Fermionic Superstring Models I: Mass Spectrum and Couplings
G. Cleaver, M. Cvetic, J. R. Espinosa +3
From the "top-down" approach we investigate physics implications of the class of D- and F- flat directions formed from non-Abelian singlets which are proven flat to all orders in t…
D-term Inflation in Superstring Theories
J. R. Espinosa, A. Riotto, G. G. Ross
An inflationary stage dominated by a -term avoids the slow-roll problem of inflation in supergravity and may emerge in theories with a non-anomalous or anomalous U(1) gauge symm…
