$\pt$-differential yield of ${\rm f_1(1285)}$ measured at midrapidity ($|y|< 0.5$) in inelastic pp collisions at $\s$ = 13 TeV. The statistical and systematic uncertainties are shown as bars and boxes, respectively. The data points are fitted using a Levy-Tsallis function and shown by the red dashed line. The BR uncertainty for ${\rm f_1(1285)} \rightarrow {\rm K^0_S K^\pm} \pi^\mp$ is 0.1%.
