Description
In this talk, I will discuss the spectacular collider signatures of macroscopically long-lived, neutral particles that decay to Higgs boson and missing energy. I show that such long-lived particles arise naturally in a very minimal extension of the Standard Model with only two new fermions with electroweak interactions. The lifetime of the longlived neutral fermion can range from less than 0.1 mm to several meters, and in some regions of the parameter space, the exotic signals would have already been selected by the ATLAS and CMS triggers in their 7 and 8 TeV runs, hence hiding in the existing data. I will also discuss the implications for the Higgs and diboson phenomenology in the presence of these new electroweak states.
