Higgs doublet as a Goldstone boson in perturbative extensions of the Standard Model
Brando Bellazzini, Stefan Pokorski, Vyacheslav S. Rychkov +1
We investigate the idea of the Higgs doublet as a pseudo-Goldstone boson in perturbative extensions of the Standard Model, motivated by the desire to ameliorate its hierarchy probl…
Gravitational corrections to Standard Model vacuum decay
Gino Isidori, Vyacheslav S. Rychkov, Alessandro Strumia +1
We refine and update the metastability constraint on the Standard Model top and Higgs masses, by analytically including gravitational corrections to the vacuum decay rate. Present…
An alternative NMSSM phenomenology with manifest perturbative unification
Riccardo Barbieri, Lawrence J. Hall, Anastasios Y. Papaioannou +2
Can supersymmetric models with a moderate stop mass be made consistent with the negative Higgs boson searches at LEP, while keeping perturbative unification manifest? The NMSSM ach…
The Higgs boson from an extended symmetry
Riccardo Barbieri, Brando Bellazzini, Vyacheslav S. Rychkov +1
The variety of ideas put forward in the context of a "composite" picture for the Higgs boson calls for a simple and effective description of the related phenomenology. Such a descr…
Thermal production of gravitinos
Vyacheslav S. Rychkov, Alessandro Strumia
We reconsider thermal production of gravitinos in the early universe, adding to previously considered 2 -> 2 gauge scatterings: a) production via 1 -> 2 decays, allowed by thermal…
Tests of Classical Gravity Description for Microscopic Black Hole Production
Vyacheslav S. Rychkov
The classical Einstein gravity description of black hole production in transplanckian collisions in TeV-scale gravity is tested for self-consistency. In addition to the "curvature…
