Probing vorticity structure in heavy-ion collisions by local $\Lambda$ polarization

Xiao-Liang Xia, Hui Li, Zebo Tang +1

We study the local structure of the vorticity field and the $\Lambda$ polarization in Au+Au collisions in the energy range $\sqrt{s_{\mathrm{NN}}}=7.7$--$200$ GeV and Pb+Pb collisions at…
