A Review of Elliptic Flow of Light Nuclei in Heavy-Ion Collisions at RHIC and LHC Energies

We present a review of the measurements of elliptic flow (V-2) of light nuclei (d,(d) over bar ,t, He-3, and (3)(He) over bar) from the RHIC and LHC experiments. Light (anti) nuclei V-2 have been compared with that of (anti) proton. We observed a similar trend in light nuclei V-2 to that in identified hadron V-2 with respect to the general observations such as P-T dependence, low P-T mass ordering, and centrality dependence. We also compared the difference of nuclei and antinuclei V-2 with the corresponding difference of V-2 of proton and antiproton at various collision energies. Qualitatively they depict similar behavior. We also compare the data on light nuclei V-2 to various theoretical models such as blast-wave and coalescence. We then present a prediction of V-2 for He-3 and He-4 using coalescence and blast-wave models.
