$v_2$ in high-multiplicity p--Pb collisions. $p_{\rm T}$-differential $v_2$ measured with two-particle correlation for mesons ($\pi^\pm$, ${\rm K}^\pm$, ${\rm K}^0_{\rm S}$) and baryons (${\rm p}^+\bar{\rm p}$, $\Lambda+\bar{\Lambda}$) in high-multiplicity p--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV. Horizontal bars (boxes) represent the statistical (systematic) uncertainties. Comparisons with the calculations from the Hydro-Coal-Frag model (left) and the Hydro-Frag model (right) are also presented. Only statistical uncertainties are shown for the calculations.
