Long Lived Fourth Generation and the Higgs
Wai-Yee Keung, Pedro Schwaller
A chiral fourth generation is a simple and well motivated extension of the standard model, and has important consequences for Higgs phenomenology. Here we consider a scenario where…
Multi-Photon Signals from Composite Models at LHC
Ayres Freitas, Pedro Schwaller
We analyze the collider signals of composite scalars that emerge in certain little Higgs models and models of vectorlike confinement. Similar to the decay of the pion into photon p…
Muon Excess in Cosmic Rays and at CDF: Signs for a Hidden Sector?
Thomas Gehrmann, Nicolas Greiner, Pedro Schwaller
In this letter we discuss a certain class of Hidden Valley models where the dynamics in the hidden sector are close to a strongly coupled conformal fixed point. We show that these…
Consequences of T-parity breaking in the Littlest Higgs model
A. Freitas, P. Schwaller, D. Wyler
In this paper we consider the effects of the T-parity violating anomalous Wess-Zumino-Witten-Term in the Littlest Higgs model. Apart from tree level processes, the loop induced dec…
