Proposing strongly interacting massive particles as dark matter candidates introduces a fascinating collider signature known as semi-visible jets. This study is a continuation of the first search for non-resonant production of SVJs, setting the first upper limits for strongly coupled dark sectors for a bi-fundamental mediator mass up to 2.7 TeV. The new search strategy for semi-visible jet production, in contrary to looking at democratic production of all five quark flavors along with dark matter particles, the focus is on semi-visible jet production along with just bottom quarks. The first step was to probe if this signal has been excluded by any current search at the LHC, involving MET and b-jets. A thorough literature review yielded few potential papers which probes a similar final state as this signal, namely, the search for dark matter produced in association with a Standard Model Higgs boson decaying into b-quarks and the search for SUSY in final states with MET and three or more b-jets. These searches are not sensitive to our signal. The second step was to make use of variable-R jet clustering to better reconstruct the signal.
