Decay angular distributions of $K^{\ast }$ and $D^{\ast }$ mesons as a tool for the dynamics of open strange and charm production

Sang-Ho Kim, Yongseok Oh, Alexander I. Titov

We analyze decay spin-density matrix elements of $K^{\ast }$ and $D^{\ast }$ vector mesons and find that the corresponding vector meson decay distributions are sensitive to the production mech…
