We present preliminary two-particle correlations for unidentified hadrons in p--p collisions at \sqrt {s}=200 GeV. On two-particle transverse rapidity space y_t \otimes y_t two distinct regions of correlated pairs are observed: a peaked structure at low y_t (p_t\leq 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\simeq 2.8 (p_t1,p_t2 \simeq 1.2 GeV/c). We select those regions separately, projecting correlations onto momentum-difference variables (\eta _{{ \Delta }},\phi _{{ \Delta }}), and observe structures interpretable in the context of string and parton fragmentations from soft and semi-hard components of p--p collisions.
