Charged particle multiplicity in pp-collisions from the dilute Glasma

High Energy Physics - Phenomenology 2025-02-25 v1

Abstract

Proton-proton collisions are studied in the dilute Glasma framework. Compared to experimental multiplicity distributions, the dilute Glasma underestimates large multiplicity events. We show how event-by-event fluctuations of the saturation momentum Qs can help repair the multiplicity distribution. Furthermore, we discuss a hot spot model for protons and also find improvements in the multiplicity histograms.
