Description

The system created in ultrarelativistic non central heavy-ion collisions exhibits a large orbital angular momentum. We have presented the measurements of spin alignment of K*0 and polarization of Λ. The measured polarization values of Λ hyperons are consistent with zero within the precision of the measurement and follow the trend of polarization decreasing with increasing energy as observed by the STAR collaboration. The measured value of ρ00 for K*0 vector meson is less than 1/3 for pT < 2 GeV/c hinting at a possible spin alignment in Pb-Pb collisions at √sNN = 2.76 TeV
