  1. 64. Probing partonic collectivity in pp and p--Pb collisions with ALICE
    Wenya Wu (Fudan University (CN))

    Collective dynamics from small to large systems
    Oral

    Long-range azimuthal angle correlations of the produced particles have been observed in high multiplicity proton--lead (p--Pb) and proton--proton (pp) collisions, indicating the presence of collective effects in small systems. The origin of these effects is the subject of intense debate.

    In this talk, we present the measurements of $v_{\rm n}$ of charged particle pairs and identified...

  2. 81. Systematic study of flow harmonics via di-hadron correlations at mid-rapidity in p+Au, d+Au and ^{3}He+Au collisions at 200 GeV

    Collective dynamics from small to large systems
    Oral

    How collectivity originates and evolves in the collisions of small-size systems is a highly debated topic in the heavy-ion community. The evolution may be associated with both hydrodynamic and non-hydrodynamic modes. Furthermore, the uncertainties in the description of initial geometry and fluctuations at the sub-nucleonic scale will significantly degrade the predictive power of the available...

  3. 34. Multiparticle cumulants in 13 TeV p+p collisions and effects of the proton substructure from a transport model

    Collective dynamics from small to large systems
    Oral

    Flow-like signals including the ridge structure observed in large collision systems have also been observed in small collision systems. This leads to questions about the onset of collectivity as well as the parton phase in nuclear collisions. Here [1], we use the string melting version of a multi-phase transport (AMPT) model to study multiparticle cumulants in p+p collisions at 13 TeV. The...

  4. 108. Anisotropic flow in small systems
    Dr Wilke Van Der Schee (CERN)
    21/06/2023, 15:00
    Collective dynamics from small to large systems
    Oral

    Small systems display large anisotropic flow coefficients that can potentially be interpreted as a hydrodynamic signal. At these moderate multiplicities anisotropic flow is however relatively sensitive to subtle effects. These include the precise experimental procedure, rapidity coverage and gaps as well as effects due to resonance decays. In this talk we quantify these effects for pPb, OO and...

  5. 89. Exploring the importance of quark recombination in high multiplicity small system collisions
    Huichao Song, Yuanyuan Wang (Peking University)
    21/06/2023, 15:20
    Collective dynamics from small to large systems
    Oral

    Particle production and collective flow of identified hadrons over the $p_{\rm T}$ range from 0 to 6 GeV in high multiplicity events of proton-proton and proton-lead collisions at the Large Hadron Collider (LHC) are investigated by Hydro-Coal-Frag model, which includes hydrodynamic models at low transverse momentum, quark recombination model at intermediate transverse momentum, and string...
