  1. 59. Measurement of global and local spin polarization of $\Lambda$ and $\bar{\Lambda}$ in Au+Au collisions from the RHIC Beam Energy Scan-II (online)

    Significant global hyperon polarization has been observed in non-central heavy ion collisions, providing evidence of the vorticity of the quark-gluon plasma (QGP). This effect can serve as a new probe for exploring the fluid properties of strongly interacting matter. A difference between the global polarization of $\bar{\Lambda}$ and $\Lambda$ could originate from the strong late-stage...

  2. 44. Hyperon polarization along the beam direction in pPb collision at CMS (online)

    On-line talk

    The observation of hyperon polarization along beam direction ($P_z$) in nucleus-nucleus collisions has opened a new way to study the complex vortical structures of the QGP. With the high-statistics data collected by the CMS experiment, we present the first $P_z$ results for $\Lambda$ and $\bar{\Lambda}$ particles in pPb collision at $\sqrt{s_{NN}}= 8.16$ TeV over a wide transverse momentum and...

  3. 52. Global Hypertriton Polarization in Au+Au collisions at $\sqrt{s_{NN}}=7.7-200$ GeV (online)
    Dai-Neng Liu
    7/24/24, 12:00 PM
    On-line talk

    Particles of non-zero spin produced in non-central heavy-ion collisions are expected to be polarized along the direction perpendicular to the reaction plane due to spin-orbit coupling in the produced matter, and this has indeed been observed for many hyperons and vector mesons. Here, we show that the hypertriton ($_\Lambda^3$H), which is the lightest hypernucleus, is also polarized in these...

  4. 79. Lambda-(anti)Lambda Spin Correlation in Heavy-Ion Collisions
    Xin-Nian Wang (Central China Normal University)
    7/24/24, 12:30 PM
    Talk

    Recent experimental data indicate a strong phi vector meson spin alignment which can be explained as a result of a short distance correlation of fluctuating strong-force field. If such strong-force for strange quark exists in the late stage of heavy-ion collisions, it will also lead to spin-spin correlation of final state hyperons such as Lambda-(anti)Lambda. We calculate such spin-spin...
