Spin alignment of vector mesons and hyperon polarization in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV

We have presented the measurements of spin alignment of $K^{∗0}$ and polarization of $\Lambda$. The measured polarization values of $\Lambda$ hyperonsare consistent with zero within the precision of the measurement and follow the trend of polarization decreasing with increasing energyas observed by the STAR collaboration. The measured value of $ρ_{00}$ for $K^{∗0}$ vector meson isless than 1/3 for $pT$ < 2 GeV/$c$ hinting at a possible spin alignment in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV.
