Semivisible jets are large area jets containing missing transverse momentum. These jets could be caused by a QCD-like dark sector, coupled to the SM via an additional Z' boson. The dark sector contains dark quarks, which while hadronizing form both stable and unstable dark hadrons. This hadronization process leads to large jets containing both SM particles and invisible DM particles.
This search uses data scouting, a technique that utilizes HLT reconstruction to access otherwise lost events below the typical trigger thresholds, to expand the parameter space of the existing s-channel search for a resonant Z' decaying into two semivisible jets.
This talk will present the search strategy, status and expected limits for the search for semivisible jets using scouting data collected by the CMS experiment during Run 2 of the LHC.
