  1. 236. Search for jet quenching effects in high multiplicity proton-proton collisions at $\sqrt{s}=13$ TeV with ALICE

    Oral Presentation

    The ALICE Collaboration reports a search for jet quenching effects in high multiplicity pp collisions at $\sqrt{s}$ = 13 TeV, utilizing the semi-inclusive distribution of charged-particle jets recoiling from a high transverse momentum charged-hadron trigger. The multiplicity is measured using forward scintillation detectors that are separated in phase-space from the central region where the...

  2. 129. Collective behavior of high-$p_{T}$ particles in 8.16 TeV $p$+Pb collisions with the ATLAS detector

    Oral Presentation

    Charged particles in small collision systems such as $pp$ and $p$+Pb have been observed to have significant azimuthal modulations of their momenta, commonly interpreted as flow, up to a transverse momentum of $p_{T} \approx 10$~GeV. In large collision systems such as Pb+Pb, lower but non-zero flow coefficients at higher $p_{T}$ ($> 10$~GeV) are usually understood to reflect jet quenching, and...

  3. 597. Probing the partonic degree of freedom in high multiplicity p-Pb at  $\sqrt{s}$=  5.02 TeV collisions.

    Small systems
    Oral Presentation

    The collective flow and the possible formation of the Quark-Gluon Plasma (QGP) in the small colliding systems are hot research topics in the heavy-ion community. Recently, ALICE, ATLAS and CMS collaborations have measured the elliptic flow and the related number of constituent quark (NCQ) scaling of identified hadrons in p+Pb collisions at $\sqrt{s}$ = 5.02 TeV, which are important...

  4. 105. Ultracentral Collisions of Small and Deformed Systems at RHIC
    Douglas Wertepny (Ben Gurion University of the Negev)

    Small systems
    Oral Presentation

    We study a range of collision systems involving deformed ions and compare the elliptic and triangular flow harmonics produced in a hydrodynamics scenario versus a color glass condensate (CGC) scenario. For the hydrodynamics scenario, we generate initial conditions using TRENTO and work within a linear response approximation to obtain the final flow harmonics. For the CGC scenario, we use the...

  5. 439. Correlation measurements of charged particles and jets at mid-rapidity with event activity at backward-rapidity in $\sqrt{s_\mathrm{NN}}=200$ GeV p+Au collisions at STAR
    David Stewart for the STAR Collaboration (Yale University)
    11/5/19, 12:20 PM
    Small systems
    Oral Presentation

    Recent measurements of small system collisions, p+p and p+A, show signals which, in A+A collisions, had been attributed to the formation of a strongly interacting medium. These notably include flow-like correlations. However, so far no clear demonstration of jet energy losses in small system collisions have been observed.

    In this talk, we will present correlations of mid-rapidity charged...
