Flow in collisions of light nuclei

In this talk we discuss several interesting aspects of collective flow in small systems in reference to planned future experiments. First, we bring in the novel possibility of exploring elliptic flow with heavy nuclei collisions on polarized deuteron targets, accessible in AFTER@LHC program after Long Shutdown 3. Then we pass to the Glauber model predictions for the presently considered ${}^{16}{\rm O}-{}^{16}{\rm O}$ program and RHIC and the LHC. Finally, we turn to our previous proposal concerning specific flow signatures of intrinsic correlations (such as the supposed $\alpha$ clusterization) in the structure of light nuclei in collisions with heavy nuclei. In particular, ${}^{12}{\rm C}$--heavy nucleus ultrarelativistic reactions would provide insight into the ground-state ${}^{12}{\rm C}$ structure, complementary to the traditional nuclear structure features.
