ABSTRACT:
As the LHC bounds on stops and t-primes tighten, theories of 'neutral naturalness,' where the little hierarchy between the weak scale and an ultraviolet (UV) scale of 5-10 TeV is stabilized by color-less top partners, are receiving new attention. The prime example in this class is the Twin Higgs model. In many of its UV completions, exotic fermions charged under both the Standard Model and twin gauge symmetries appear. Some of these new fermions carry visible color, thus providing a novel portal to access the twin sector at hadron colliders. Spectacular displaced signals are possible, and in some cases required for cosmological reasons. I will discuss these signatures at the LHC and future colliders, arguing that they provide a strong test of the UV completion of Twin Higgs.
