$p_{\rm T}$-differential yield of ${\rm f}_1(1285)$ measured at midrapidity ($|y|$ < 0.5) in inelastic pp collisions at $\sqrt{s} = 13$ TeV. The statistical and systematic uncertainties are shown as bars and boxes, respectively. The data points are fitted using a Levy-Tsallis function [89] and shown by the red dashed line. The BR uncertainty for ${\rm f}_1(1285) \longrightarrow {\rm K}^0_{\rm S}{\rm K}^{\pm}\pi^{\mp}$ is 0.1%.
