  Semi-visible jets arise in strongly interacting dark sectors, resulting in
jets overlapping with missing transverse momentum direction. The implementation
of semi-visible jets is done using the Pythia Hidden Valley module to mimic the
QCD sector showering in so-called dark shower. In this work, only heavy flavour
Standard Model quarks are considered in dark shower, resulting in a much less
ambiguous collider signature of semi-visible jets compared to the democratic
production of all five quark flavours in dark shower. The constraints from
available searches on this signature are presented, and it is shown the signal
reconstruction can be improved by using variable-radius jets. Finally a search
strategy is suggested.
