Résumé

Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum.The implementation of semi-visible jets is done using the Pythia Hidden valley module to duplicate the QCD sector showering.In this work, several jet substructure observables have been examined to compare semi-visible jets (signal) and light quark/gluon jets (background).These comparisons were performed using different dark hadron fractions in the semi-visible jets.The extreme scenarios where signal consists either of entirely dark hadrons or visible hadrons offers a chance to understand the effect of the specific dark shower model employed in these comparisons.We attempt to decouple the behaviour of jet-substructure observables due to inherent semi-visible jet properties, from model dependence owing to the existence of only one dark shower model as mentioned above.
