The Little Skyrmion: New Dark Matter for Little Higgs Models
(Springer Verlag, 2012-03)
We study skyrmions in the littlest Higgs model and discuss their possible role as dark matter candidates. Stable massive skyrmions can exist in the littlest Higgs model also in absence of an exact parity symmetry, since ...
Dark side of the Higgs boson
(American Physical Society, 2012-01)
Current limits from the Large Hadron Collider exclude a standard model-like Higgs mass above 150 GeV, by placing an upper bound on the Higgs production rate. We emphasize that, alternatively, the limit could be interpreted ...
Dark Matter and enhanced h -> gamma gamma rate from vector-like Leptons
(Springer Verlag, 2012-12)
In this paper, we study an extension of the standard model with a vector-like generation of leptons. This model provides a viable dark matter candidate and a possibility to enhance the Higgs decay rate into a pair of ...
Looking for a light Higgs boson in the Zγ→ℓℓγ channel
(American Physical Society, 2012-08)
The final state obtained when a Higgs boson decays to a photon and a Z boson has been mostly overlooked in current searches for a light Higgs boson. However, when the Z boson decays leptonically, all final state particles ...
