How does plasma melt the internal structure of speeding jets?

When jets from particle collisions pass through the hot quark-gluon plasma in heavy-ion collisions, their internal structure gets modified. Researchers used the CoLBT-hydro model to track how this happens across different scales and reproduced recent CMS measurements of energy correlations inside jets. The calculations reveal that longer paths through the plasma cause greater reshaping, and they validate experimental background-subtraction techniques used to isolate the plasma's effect.
