Non-photonic electron-hadron correlations at STAR

We present STAR’s measurements of azimuthal correlations between nonphotonic electrons and charged hadrons in p+p, Cu+Cu and Au+Au collisions at √ sNN = 200 GeV. In p+p collisions, from the non-photonic e-h correlation we have extracted the relative B meson semi-leptonic decay contributions to non-photonic electrons up to electron pt ∼ 9 GeV/c. In central Cu+Cu and Au+Au collisions where a dens...

γ-hadron azimuthal correlations in STAR

One of the most exciting results at RHIC is the suppression of hadrons in central Au+Au collisions, compared to p+p collisions [1] and to cold nuclear matter [2] at high pT . This suppression is well described by very different pQCD-based energy loss models in the light flavor sector [3] . However, the observation of a similar level of suppression for the heavy flavor [4], and the unexpected sm...

Parton Models and Deep Hadron - Hadron Scattering

We review the recent applications of various parton models, to the problem of hadron-hadron scattering at large momentum transfers. Models which allow direct parton-parton interactions as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplicities, and the s and t dependencies of inclusive and...
