      abstract     = {We present the measurement of the p$_T$-differential
                      production cross section of ω mesons in pp and p-Pb
                      collisions at $\sqrt{s_{NN}}$ = 5.02 TeV at midrapidity by
                      ALICE. In addition, the first measurement of the nuclear
                      modification factor R$_{pPb}$ for ω mesons at LHC energies
                      is presented, complementing the existing measurements of
                      lighter neutral mesons such as the π$^0$ and η. Within the
                      measured p$_T$ range, the R$_{pPb}$ of ω mesons is
                      compatible with no cold nuclear matter effects within the
                      uncertainties, consistent with previous measurements at
                      lower energies. The ω/π$^0$ ratio is presented for both
                      collision systems, showing no collision system dependence
                      within the uncertainties. The comparison to previously
                      published ω/π$^0$ ratios at lower and higher collision
                      energies in pp collisions suggests a decreasing trend of the
                      ratio above p$_T$ = 4 GeV/c 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’ ability to describe the production of ω mesons.},
