LHCb: Correlations show nuances of the particle birth process

High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born from this plasma? Further clues in the search for answers to these questions are provided by the latest analysis of collisions between protons and protons or ions, observed in the LHCb experiment.
