摘要：
In ultra-peripheral collisions (UPC), exclusive vector meson photoproduction, such as rho(0) and J/Psi, serves as a sensitive probe for studying the gluon structure in heavy nuclei. The linear polarization of the photons involved in these processes help to image the nucleus through the so-called entanglement-enabled spin interference in vector meson photoproductions. The photoproduced J/Psi has longer lifetime (2160 fm/c) and non-localized wave function which provides unique opportunity to study the entanglement between the photon and the Pomeron phases emitted from each nucleus. We present the first measurement of the interference pattern for the photoproduced J/Psi in Au+Au UPC at v root s (NN) = 200 GeV with the STAR experiment.
