Description
Oxygen-oxygen (OO) collisions offer a unique opportunity to investigate collectivity and signatures of the medium formed in a smaller collision system compared to the heavy-ion systems such as Pb--Pb. The elliptic flow coefficient $v_2$ is a key observable sensitive to the initial collision geometry and the subsequent evolution of the system. In this context, quarkonia, and in particular the $J/\psi$ meson, are excellent probes of the medium due to their early production and their interaction with the surrounding medium. Collisions of light nuclei further allow exploration of whether charm quarks exhibit signs of thermalization in small systems. By comparing the $J/\psi$ $v_2$ measurements in OO collisions with measurements from larger collision systems, the scaling of quarkonium collectivity with system size can be explored.
In this contribution, the first measurement of the azimuthal-anisotropy coefficient $v_2$ of inclusive $J/\psi$ in OO collisions at $\sqrt{s_{NN}}$ = 5.36 TeV at midrapidity using the ALICE experiment data will be presented. The $v_2$ values are extracted in several transverse-momentum and centrality intervals using the scalar product method. The contribution outlines the full analysis procedure including the signal extraction and flow determination.
