Search for dark jets in pp collisions at 13.6 TeV with the ATLAS experiment

The Standard Model of particle physics is currently the most complete theory of the elementary particles and their interactions in our Universe. However, many open questions and observed phenomena suggest that the Standard Model is an effective theory, valid only at the energies we can probe on Earth. The search for solutions to Standard Model problems is one of the main goals of modern particle physics. One of such open issues is the nature of Dark Matter: this is a form of matter that interacts gravitationally but that cannot be observed via electromagnetic interactions, that is why it is called “dark”. My research activity will focus on a model that predicts the existence of new particle mediators called “portals”, that connect Dark Matter to Standard Model. Decays of these portals will lead to unstable Dark Matter particles, called “dark hadrons”, which may decay into Standard Model particles that can be observed. This analysis will be conducted in the context of the ATLAS experiment at CERN, using a detailed Monte Carlo simulation of the experiment and the data acquired from the proton-proton collisions at a center-of-mass energy of 13.6 TeV.
