abstract = {CERN-LHC. Neutral pion (π$^0$) and η meson production
cross sections were measured up to unprecedentedly high
transverse momenta (p$_T$) in p–Pb collisions at
$\sqrt{s_{\rm NN}}$ = 8.16TeV. The mesons were reconstructed
via their two-photon decay channel in the rapidity interval
−1.3 < y < 0.3 in the ranges of 0.4 < p$_T$ < 200 GeV/c
and 1.0 < p$_T$ < 50 GeV/c, respectively. The respective
nuclear modification factor (R$_{pPb}$) is presented for
p$_T$ up to of 200 and 30 GeV/c, where the former was
achieved by extending the π$^0$ measurement in pp
collisions at $\sqrt{s}$ = 8TeV using the merged cluster
technique. The values of R$_{pPb}$ are below unity for p$_T$
< 10 GeV/c, while they are consistent with unity for p$_T$ >
10 GeV/c, leaving essentially no room for final state energy
loss. The new data provide strong constraints for nuclear
parton distribution and fragmentation functions over a broad
kinematic range and are compared to model predictions as
well as previous results at $\sqrt{s_{\rm NN}}$ = 5.02TeV.},
