Searching for Displaced Higgs Decays
Abstract
We study a simplified model of the SM Higgs boson decaying to a degenerate pair of scalars which travel a macroscopic distance before decaying to SM particles. This is the leading signal for many well-motivated solutions to the hierarchy problem that do not propose additional light colored particles. Bounds for displaced Higgs decays below 10 cm are found by recasting existing tracker searches from Run I. New tracker search strategies, sensitive to the characteristics of these models and similar decays, are proposed with sensitivities projected for Run II at s = 13 TeV. With 20 fb-1 of data, we find that Higgs branching ratios down to 7 × 10-4 can be probed for centimeter decay lengths.
