Measurement of ω meson production in pp and p-Pb collisions at √sNN=5.02 TeV
Original language description
We present the measurement of the p(T)-differential production cross section of omega mesons in pp and p-Pb collisions at root s(NN) = 5.02 TeV at midrapidity by ALICE. In addition, the first measurement of the nuclear modification factor R-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(T) range, the R-pPb of omega mesons is compatible with 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(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 omega mesons.
