Anisotropic flow of identified hadrons in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.44TeV

Abstract

Measurements of elliptic ($v_2$) and triangular ($v_3$) flow coefficients of ${\pi }^{\pm }$, K${}^{\pm }$, p+$\overline{\mathrm{p}}$, K${}_{\mathrm{S}}^0$, and $\Lambda +\overline{\Lambda }$ obtained with the scalar product method in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.44 TeV are presented. The results are obtained in the rapidity range $\left|y\right|<0.5$ and reported as a function of transverse momentum, $p_{\mathrm{T}}$, for several collision centrality classes. The flow coefficients exhibit a particle mass dependence for $p_{\mathrm{T}}<3$ GeV/$c$, while a grouping according to particle type (i.e., meson and baryon) is found at intermediate transverse momenta (3< $p_{\mathrm{T}}$ <8 GeV/$c$). The magnitude of the baryon $v_2$ is larger than that of mesons up to $p_{\mathrm{T}}$ = 6 GeV/$c$. The centrality dependence of the shape evolution of the $p_{\mathrm{T}}$-differential $v_2$ is studied for the various hadron species. The $v_2$ coefficients of ${\pi }^{\pm }$, K${}^{\pm }$, and p+$\overline{\mathrm{p}}$ are reproduced by MUSIC hydrodynamic calculations coupled to a hadronic cascade model (UrQMD) for $p_{\mathrm{T}}<1$ GeV/$c$. A comparison with $v_{\mathrm{n}}$ measurements in the corresponding centrality intervals in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV yields an enhanced $v_2$ in central collisions and diminished value in semicentral collisions.
