Description
Emerging jets are jets with multiple displaced tracks, which originate from the decay of long-lived bound states of a strongly interacting dark sector. In this talk I will summarize our attempts to "validate" the CMS emerging jet search, showing that we are able to reproduce, within reasonable accuracy, the limits obtained by the CMS collaboration in their benchmark model.
The derived efficiencies are then used to consider a novel emerging jet scenario, namely using the SM Higgs exotic decay into a pair of long-lived "dark pions". We find that emerging jets can be the leading probe in regions of parameter space, being able to probe at the HL-LHC exotic Higgs branching ratios below the 1\% level, which is below the "undetected" exotic Higgs decays expectation of 2.5 - 4 %.
