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