Measurement ofKS0andK*0inp+p,d

Abstract

The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a systematic that cold-nuclear-matter effects do not play a significant role in the measured kinematic range. 167In Cu+Cu collisions, within the uncertainties no nuclear modification is registered in peripheral particles is similarly suppressed by a factor of ≈ 2. 174PACS numbers: 25.75.Dw

$$K^{*}(892)^0$$ meson production in inelastic p+p interactions at 40 and 80 $$\text{ GeV }\!/\!c$$ beam momenta measured by NA61/SHINE at the CERN SPS

“…The analysis of K * (892) 0 and/or K * (892) 0 production in p+p interactions at RHIC energies was reported by the STAR [11] and PHENIX [12] experiments and at LHC energies by ALICE [13][14][15][16][17][18][19]. The NA49 and NA61/SHINE experiments published such measurements for inelastic p+p collisions at 158 GeV/c beam momentum (CERN SPS) [9,10].…”

$\mathrm{K}^{*}(\mathrm{892})^{0}$ and $\mathrm{ϕ(1020)}$ production in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 8.16 TeV

“…They play an important role to understand the particle production mechanisms and for the characterization of the dynamic evolution of the system formed in heavy-ion collisions. They are used as a sensitive probe of the hadronic phase, where their mass, width and yield could be modified due to interaction of their decay products through re-scattering and regeneration processes [4][5][6][7][8][9][10][11][12][13][14][15]. ALICE has previously measured K * (892) 0 and φ (1020) production in pp collisions at √ s = 5.02, 7, 8 and 13 TeV [16][17][18][19][20][21][22], in p-Pb collisions at √ s NN = 5.02 TeV [23] and Pb-Pb collisions at √ s NN = 2.76 and 5.02 TeV [13,15,18,19].…”

“…Proton-lead collisions are intermediate between pp and Pb-Pb collisions in terms of the size of the colliding system and the produced particle multiplicities. Recent measurements in high-multiplicity pp, p-Pb and d-Au collisions at different energies have uncovered strong flow-like effects even in these small collision systems [14,[22][23][24][25], whose origin is not fully understood. To investigate the mechanism of particle production and the origin of these effects, the ALICE Collaboration has studied the multiplicity dependence of light-flavor particle production for many species like π ± , K ± , K 0 S , K * (892) 0 , φ (1020), Λ, Λ(1520), Σ * ± , Ξ ± , Ξ * 0 , Ω ± in p-Pb collisions at √ s NN = 5.02 TeV [23,[26][27][28][29] and in pp collisions at √ s = 7 and 13 TeV [17,20,22,30].…”

PHENIX measurements of nuclear modification factor of hadrons in d+Au and A+A collisions.

“…R AB measurements in d+Au collisions Figure 1: Nuclear modification factor as a function of p T for photons [5], electrons from heavy flavor [4], light and strange mesons [6] and also protons [7] (for the (a) most central and (b) peripheral centrality bin) in d+Au collisions at √ s NN = 200 GeV. The statistical errors are shown by bars and the systematic errors are shown by boxes.…”

“…The statistical errors are shown by bars and the systematic errors are shown by boxes. Figure 1 shows the nuclear modification factor of photons [5], electrons from heavy flavor (e − HF ) [4], light mesons, strange mesons [6,7] and protons in d+Au collisions at √ s NN = 200 GeV. It is observed that for photons and light mesons, R dAu ∼ 1 within uncertainties, for p T > 2 GeV/c, which indicates that these particles do not suffer any kind of cold nuclear matter effects.…”
