Medium anisotropy in p–O and p–C collisions at the LHC with exotic α[jls-end-space/]-clustered nuclear density profiles

Abstract

To explore small system collectivity and the effects of α[jls-end-space/]-clustered nuclear configurations on the final state anisotropic flow coefficients vn[jls-end-space/], we perform a systematic study for the first time, on p–O and p–C collisions at (Formula presented) TeV using a multi-phase transport (AMPT) model. We employ the two-particle Q-cumulant method to estimate elliptic (v2[jls-end-space/]) and triangular (v3[jls-end-space/]) flow. The transverse momentum (pT[jls-end-space/]) and pseudorapidity (η[jls-end-space/]) spectra, eccentricity and triangularity, v2 and v3 are then elaborately studied as a function of centrality, collision species, and nuclear density profiles. This work, thus, serves as a transport model-based prediction for the upcoming p–O collisions at the Large Hadron Collider (LHC). © 2025 Elsevier Ltd.
