Creation of light hadrons in Cu + Au interactions at an energy of 200 GeV

Abstract

Collisions between asymmetric nuclei (Cu–Au) differ significantly in their nuclear overlap geometry from those of symmetric nuclei (Cu–Cu, Au–Au). This results in a number of consequences that allow us to obtain more comprehensive and accurate information about the fundamental properties of matter under extreme conditions. The High Energy Proton–Proton Collider Experiment (PHENIX) at the Relativistic Heavy Ion Collider (RHIC) measured the nuclear modification factors of π-mesons in Cu+Au collisions at an energy of 200 GeV. New experimental data from measurements of light hadron flows of different orders (ν1, ν2) in Cu + Au collisions at an energy of 200 GeV are discussed.
