2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/176818We present the preliminary measurement of azimuthal correlations between non-photonic electrons and charged hadrons in p+p collisions at $\sqrt{s_{NN}} = 200$ GeV from STAR. The results are compared to PYTHIA simulations to estimate the relative contributions of $D$ and $B$ meson semi-leptonic decays to the non-photonic electrons.4 pages, 3 figures, Hard Probes 2006 proceedings, to appear in Nuclear Physics ANuclear Experimenttext
