In heavy ion collisions particle distributions fluctuate from event to event. It is interesting to study local fluctuations of a specific particle specie, e.g. baryons, in the transverse plane. Fluctuations of the harmonic flow provide an…
The magnitude of the local fluctuations of the net baryon number and electric charge differs widely between the confined and deconfined phases, and the difference is partially frozen at an early stage in relativistic heavy ion collisions.…
