Measurement of ω meson production in pp and p--Pb collisions at √sNN=5.02~TeV with ALICE

The ALICE experiment at the LHC investigates the properties of the hot and dense nuclear matter created in heavy-ion collisions. By comparing the particle production in pp and p–Pb collisions, possible nuclear initial state effects can be isolated. Measurements of the ω meson pT-spectra in pp and p–Pb collisions not only allow for a determination of the nuclear modification factor RₚPb, but also provide insight into the fragmentation process and serve as vital input for decay background simulations for direct photons. In this contribution, measurements of the ω meson production in pp and p–Pb collisions at √sNN=5.02~TeV are presented. This includes the signal extraction and various corrections of the ω meson yields, leading to their production cross sections and the first measured nuclear modification factor RₚPb of the ω meson at LHC energies.
