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 semivisible 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 jetsubstructure observables due to inherent semi-visible jet properties, from model dependence owing to the existence of only one dark shower model as mentioned above.
