Methods for Centrality Determination in the BM@N Experiment
摘要
Abstract—
The strongly-interacting matter created in a relativistic heavy-ion collision depend on collision geometry, defined by centrality. Experimentally, the centrality can be estimated by the measured multiplicity of produced particles. The correlation between the impact parameter and the experimentally measured multiplicity is determined using a Monte-Carlo version of the Glauber model or a Γ-fit method based on Bayes’ inverse theorem. In this work, we test procedure of centrality determination using multiplicity of particles produced in Xe + Cs(I) collisions at the BM@N experiment.
