Abstract

Semi-visible jets arise in strongly interacting dark sector, resulting in jets overlapping with the 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.

Author comments upon resubmission

We thank the referees for comprehensive reviews, and making suggestions to improve the quality and usefulness of the paper. We apologise for the delay in getting back, summer travels came in the way. We tried to address most of the concerns.

List of changes

* Reorganised the model part, switched from NF_1 to NF_2 for theoretical consistency, but none of the conclusions change.
* Added plots of a couple of new discriminating variables, and proposed a loose set up cuts for an experiment analysis with a cutflow. Also expanded the text to motivate the analysis strategy.
* We have added a study of a new jet reconstruction technique called the Dynamic Radius Jet Clustering.
* We added more details on the analyses used for reinterpretation to help the reader.
* Fixed typos, and textual inconsistencies.
