Spin alignment measurements of the K*0(892) and ϕ(1020) vector mesons in heavy ion collisions at sNN=200 GeV Academic Article uri icon

abstract

  • We present the first spin alignment measurements for the K*0(892) and (1020) vector mesons produced at midrapidity with transverse momenta up to 5 GeV/c at sNN=200 GeV at RHIC. The diagonal spin-density matrix elements with respect to the reaction plane in Au+Au collisions are ρ00=0.32±0.04 (stat) ± 0.09 (syst) for the K*0 (0.8
