abstract = "We present the measurement of the πT-differential production cross section of π mesons in pp and π-Pb collisions at βπ πβ’π=5.02 TeV at midrapidity by ALICE. In addition, the first measurement of the nuclear modification factor π
πβ’Pb for π mesons at LHC energies is presented, complementing the existing measurements of lighter neutral mesons such as the π0 and π. Within the measured πT range, the π
πβ’Pb of π mesons is compatible with no cold nuclear matter effects within the uncertainties, consistent with previous measurements at lower energies. The π/π0 ratio is presented for both collision systems, showing no collision system dependence within the uncertainties. The comparison to previously published π/π0 ratios at lower and higher collision energies in pp collisions suggests a decreasing trend of the ratio above πT = 4 GeV/π with increasing collision energy. The data in both collision systems are compared to predictions from PYTHIA 8, EPOS LHC, and DPMJET event generators, revealing significant shortcomings in these models{\textquoteright} ability to describe the production of π mesons.",
