Measurement of ω meson production in pp collisions at √s=13 TeV
Original language description
The p(T)-differential cross section of omega meson production in pp collisions at root s = 13 TeV at midrapidity (vertical bar y vertical bar < 0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6 < p(T)< 50 GeV/c. The meson is reconstructed via the omega -> pi(+)pi(-)pi(0) decay channel. The results are compared with various theoretical calculations: PYTHIA8.2 with the Monash 2013 tune overestimates the data by up to 50%, whereas good agreement is observed with Next-to-Leading Order (NLO) calculations incorporating omega fragmentation using a broken SU(3) model. The omega/pi(0) ratio is presented and compared with theoretical calculations and the available measurements at lower collision energies. The presented data triples the p(T) ranges of previously available measurements. A constant ratio of C-omega/pi 0 = 0.578 +/- 0.006 (stat.) +/- 0.013 (syst.) is found above a transverse momentum of 4 GeV/c, which is in agreement with previous findings at lower collision energies within the systematic and statistical uncertainties.
