Improved naturalness with a heavy Higgs boson: An alternative road to CERN LHC physics
- R. Barbieri, L. Hall, V. Rychkov
- Physics
- 23 March 2006
The quadratic divergences of the Higgs mass may be cancelled either accidentally or by the exchange of some new particles. Alternatively its impact on naturalness may be weakened by raising the Higgs…
Higgs boson from an extended symmetry
- R. Barbieri, B. Bellazzini, V. Rychkov, Alvise Varagnolo
- Physics
- 4 June 2007
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 description is given here…
Supersymmetry without a Light Higgs Boson
- R. Barbieri, L. Hall, Y. Nomura, V. Rychkov
- Physics
- 29 July 2006
Motivated by the absence, so far, of any direct signal of conventional low-energy supersymmetry, we explore the consequences of making the lightest Higgs boson in supersymmetry relatively heavy, up…

- Physics

Dark matter from an ultra-light pseudo-Goldsone-boson

Mirror World at the Large Hadron Collider
- R. Barbieri, T. Grégoire, L. Hall
- Physics
- 22 September 2005
A mirror world can modify in a striking way the LHC signals of the Higgs sector. An exact or approximate Z2 symmetry between the mirror world and our world allows large mixing between the Higgs…
