【 摘 要 】

ATLAS measurements of azimuthal correlations between particle pairs at large pseudorapidity separation in pp and p+Pb collisions are presented. The data were collected using a combination of the minimum-bias and high track-multiplicity triggers. The correlations in the "ridge" region are analysed using a new template fit method for extraction of flow harmonics. A comparison of this method with the previously used ZYAM method and a detailed study of the dependence of their results on the charged particle multiplicity and the transverse momentum of the particles forming a pair are shown.
