Scientists conducting the 'Compressed Muon Detector' experiment at CERN's Large Hadron Collider have successfully identified a very subtle signal resembling a water-like trace left behind by an object moving swiftly through a liquid. However, unlike ordinary liquid, the medium in question is an extremely hot plasma known as 'quark-gluon plasma,' a state of matter believed to have filled the universe in the moments following the Big Bang.

The study, published in the journal 'Physics Letters B,' provides the first clear evidence that the production of particles decreases slightly behind a high-energy quark as it traverses this plasma. This indicates that the quark, while moving through this primordial 'soup,' leaves behind an area akin to a shadow or a weak trace, suggesting it interacts with the medium and affects it, similar to how a fast boat leaves a wake on the surface of water.

When heavy atomic nuclei collide at speeds approaching that of light inside the collider, their components merge to form a microscopic droplet of quark-gluon plasma, reaching temperatures of trillions of degrees. This groundbreaking research not only sheds light on the fundamental structures of the universe but also enhances our understanding of the conditions that existed just after the arrival of matter in our universe, underscoring a significant advancement in particle physics.
