Multiplicity and rapidity dependence of K ∗(892) and ϕ(1020) production in p–Pb collisions at √sNN= 5.02 TeV

Summary, in English

The transverse-momentum (pT) spectra of K ∗(892)0 and ϕ(1020) measured with the ALICE detector up to pT = 16 GeV/c in the rapidity range - 1.2 < y< 0.3 , in p–Pb collisions at the center-of-mass energy per nucleon–nucleon collision sNN=5.02 TeV are presented as a function of charged particle multiplicity and rapidity. The measured pT distributions show a dependence on both multiplicity and rapidity at low pT whereas no significant dependence is observed at high pT . A rapidity dependence is observed in the pT -integrated yield (dN/dy), whereas the mean transverse momentum (⟨ pT⟩) shows a flat behavior as a function of rapidity. The rapidity asymmetry (Yasym) at low pT ( 5 GeV/ c), the QCP values are greater than unity and no significant rapidity dependence is observed. © 2023, The Author(s).
