$\langle \pt \rangle$ of $\pi$, K, and p as a function of $\avdndeta$ measured in pp collisions at $\sqrt{s}=7$ and 13 TeV . Open boxes indicate systematic uncertainties, and bars indicate the statistical ones. Colored lines represent the predictions from different tunes of PYTHIA 8 and EPOS4 for pp collisions at $\sqrt{s}=13$ TeV.
