Abstract

We present first STAR measurement on two heavy-flavor particle correlations in s=200\sqrt{s}=200 GeV p+pp+p collisions at RHIC. Heavy-flavor (charm and bottom) events are identified and separated on a statistical basis through their characteristic decay topology using azimuthal correlation of non-photonic electrons and reconstructed open charmed mesons. The results are compared to simulations from PYTHIA and MC@NLO event generators. The gluon splitting contribution is found to be small. The relative bottom contribution to the non-photonic electrons is 50\sim50% at \pT>5.5\pT > 5.5 GeV/c.
