Twin Phenomenology

Speaker: Csaba Csaki

I discuss three aspects of phenomenology of twin Higgs models. First I argue that some versions of these models will produce displaced Higgs decays and examine in detail the feasibility of discovering such displaced decays in the tracker of the LHC experiments. Second I will examine flavor bounds on composite twin Higgs models. Finally I investigate how feasible identical twin Higgs models are: the number of relativistic degrees of freedom depends strongly on the decoupling temperature which can be dialed via the structure of the twin neutrino sector.
