Uncovering Dark Matter through Semi-Visible Particle Jets and Laser Experiments.

The ATLAS Collaboration has conducted the first search for semi-visible jets, a potential signature for the presence of dark matter particles. These are hypothesized to occur when two protons interact, generating an intermediate particle that then transforms into two jets. The search sets the first limits on this specific semi-visible-jet production scenario, paving the way for more nuanced dark matter searches in the future.
