Spin alignment of vector mesons in heavy ion and proton-proton collisions
The spin alignment matrix element rho(00) for the vector mesons K{*}(0) and phi(1020) has been measured in RHIC at central rapidities. These measurements are consistent with the absence of polarization with respect to the reaction plane in mid-central Au + Au collisions whereas, when measured with r...
