Abstract

We present measurements of elliptic and triangular azimuthal anisotropy of charged particles detected at forward rapidity 1<|η|<3 in Au + Au collisions at sNN=200 GeV, as a function of centrality. The multiparticle cumulant technique is used to obtain the elliptic flow coefficients v2{2},v2{4},v2{6}, and v2{8}, and triangular flow coefficients v3{2} and v3{4}. Using the small-variance limit, we estimate the mean and variance of the event-by-event v2 distribution from v2{2} and v2{4}. In a complementary analysis, we also use a folding procedure to study the distributions of v2 and v3 directly, extracting both the mean and variance. Implications for initial geometrical fluctuations and their translation into the final-state momentum distributions are discussed.9 MoreReceived 26 April 2018DOI:https://doi.org/10.1103/PhysRevC.99.024903©2019 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCollective flowParticle correlations & fluctuationsRelativistic heavy-ion collisionsPhysical SystemsHadronsQuarksTechniquesHadron collidersNuclear Physics
