Summary
Observables sensitive to the vorticity allow us to study the fundamental property of the hot and dense nuclear matter created in high-energy nuclear collisions.Global polarization parameters of identified particles can be extracted from the azimuthal distribution of particles with respect to the event plane.The spin alignment of vector meson such as $\phi$ meson and $K^{\star}$ could be sensitive to the vorticity of the colliding system and its space-time evolution.In this presentation, we will present results from a multi-phase transport (AMPT) model that is modified to include the spin alignment information of $\phi$ and $K^{\star}$ mesons. We will discuss the extraction of spin alignment parameters from event plane reconstruction, and study how hadron interactions could influence the spin alignment observables based on final state particles.
