title: "Table 11" of "Light neutral-meson production in pp collisions at $\sqrt{s}$ = 13 TeV"

description: $x_{\rm T}$ scaled $\eta$ spectrum for pp collisions at $\sqrt{s}$ = 7 TeV, with $n = 4.91$.
description: The momentum-differential invariant cross sections of $\pi^{0}$ and $\eta$ mesons are reported for pp collisions at $\sqrt{s}$ = 13 TeV at midrapidity ($|y|$ $&lt;$ 0.8). The measurement is performed in a broad transverse-momentum range of 0.2 $&lt; p_{\rm T} &lt;$ 200 GeV/$c$ and 0.4 $&lt; p_{\rm T} &lt;$ 60 GeV/$c$ for the $\pi^{0}$ and $\eta$, respectively, extending the $\eta$ coverage of previous measurements. Transverse-mass-scaling violation of up to 60% at low transverse momentum has been observed, agreeing with measurements at lower collision energies. Transverse Bjorken $x$ ($\eta$) scaling of the $\pi^{0}$ cross sections at LHC energies is fulfilled with a power-law exponent of $n$ = 5.01$\pm$0.05, consistent with values obtained for charged pions at similar collision energies. The data is compared to predictions from next-to-leading order perturbative QCD calculations, where the $\pi^{0}$ spectrum is best described using the CT18 parton distribution function and the NNFF1.0 or BDSS fragmentation function. Expectations from PYTHIA8 and EPOS LHC overestimate the spectrum for the $\pi^{0}$ and are not able to describe the shape and magnitude of the $\eta$ spectrum. The charged-particle multiplicity dependent $\pi^{0}$ and $\eta$ $p_{\rm T}$ spectra show the expected hardening with increasing multiplicity. This is demonstrated across a broad transverse-momentum range and up to events with a charged-particle multiplicity exceeding five times the mean value in minimum bias collisions. The absolute magnitude of the $\eta/\pi^{0}$ ratio shows a dependence on the charged-particle multiplicity for $p_{\rm T}$ $&lt;$ 4 GeV/$c$, qualitatively described by PYTHIA8 and EPOS LHC due to a rising contribution from feed-down of heavier particles to the $\pi^{0}$ spectrum.
