Initial-state control of vorticity--shear competition in longitudinal $\Lambda$ polarization in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.36\mathrm{TeV}$

Simin Wu, Leyao Lin, Yilong Xie

We investigate how the transverse initial energy-density distribution controls the second sine harmonic of longitudinal $\Lambda$ polarization in Pb--Pb collisions at $\sqrt{s_{\mathrm{N…
