Measurements of second-harmonic Fourier coefficients from azimuthal anisotropies in p+p, p+Au, d+Au, and He 3 +Au collisions at sNN =200 GeV

Popis výsledku v původním jazyce

Recently, the PHENIX Collaboration has published second- and third-harmonic Fourier coefficients v2 and v3 for midrapidity (|η|<0.35) charged hadrons in 0%-5% central p+Au, d+Au, and He3+Au collisions at sNN=200 GeV, utilizing three sets of two-particle correlations for two detector combinations with different pseudorapidity acceptance [Acharya, Phys. Rev. C 105, 024901 (2022)2469-998510.1103/PhysRevC.105.024901]. This paper extends these measurements of v2 to all centralities in p+Au, d+Au, and He3+Au collisions, as well as p+p collisions, as a function of transverse momentum (pT) and event multiplicity. The kinematic dependence of v2 is quantified as the ratio R of v2 between the two detector combinations as a function of event multiplicity for 0.5<pT<1 and 2<pT<2.5GeV/c. A multiphase-transport (AMPT) model can reproduce the observed v2 in most-central to midcentral d+Au and He3+Au collisions. However, the AMPT model systematically overestimates the measurements in p+p, p+Au, and peripheral d+Au and He3+Au collisions, indicating a higher nonflow contribution in the AMPT model than in the experimental data. The AMPT model fails to describe the observed R for 0.5<pT<1GeV/c, but there is qualitative agreement with the measurements for 2<pT<2.5GeV/c
