Description
Comprehensive understanding of the origins of collectivity in small collision systems has recently become a prominent research topic of growing interest given the plethora of measurements taken at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) over the years. The $^{16}$O+$^{16}$O collision system is unique since it not only complements the flow measurements in other small systems at both RHIC and LHC but also allows one to study observables carrying the signatures of nucleon-nucleon correlations predicted by effective field theories. In this work, we present a systematic study of azimuthal correlations in O+O collisions at $\sqrt{s_{\text{NN}}} =200$ GeV considering both spherical and clustered nuclear geometries. We have simulated events using the A Multi-Phase Transport (AMPT) model to investigate centrality dependence of the geometric response to initial spatial anisotropy described by eccentricity coefficients ($\varepsilon_n$) as well as anisotropic flow coefficients ($v_n$). The clustered geometry is found to exhibit distinctive features compared to the spherical configuration. In addition to this, we compare our findings with recent STAR flow measurements for central O+O collisions.
