Exploring the interplay of helicity and global-frame spin density matrix elements

Gavin Wilks, Zhenyu Ye

A significant $\ddot{I}•$-meson global spin alignment ($\ddot{I}{}_{00}$) signal was measured in Au+Au collisions at $\sqrt{s_{NN}}\le 62$ GeV. Conventional physics mechanisms such as $s(\bar{s})$…
