Title: Correlation structures from soft and semi-hard components in p-p collisions at √s =200 GeV

Abstract

We present preliminary two-particle correlations for unidentified hadrons in p-p collisions at √s =200 GeV. On two-particle transverse rapidity space y t Ⓧ y t two distinct regions of correlated pairs are observed: a peaked structure at low y t (P t ≤ 0.4 GeV/c) and a broad structure at higher y t , where the correlation is distributed as a 2D Gaussian centered at y t1 = y t2 ≃ 2.8 (p t1 , p t2 ≃ 1.2 GeV/c). We select those regions separately, projecting correlations onto momentum- difference variables (ηΔ, φΔ), and observe structures interpretable in the context of string and parton fragmentations from soft and semi-hard components of p-p collisions.
