Hadron production in lepton-nucleus deep inelastic scattering is studied in an absorption model. In the proposed model, the early stage of hadronization in the nuclear medium is dominated by prehadron formation and absorption, controlled by flavor-dependent formation lengths and absorption cross sections. Computations for hadron multiplicity ratios are presented and compared with the HERMES exp...

We present selected recent results of multi-hadron correlation measurements in azimuth and pseudorapidity at intermediate and high pT in Au+Au collisions at √ sNN = 200 GeV, from the STAR experiment at RHIC. At intermediate pT , measurements are presented that attempt to determine the origin of the associated near-side (small ∆φ) yield at large pseudo-rapidity difference ∆η that is found to be ...

We propose a sensitive measurement of the charm total cross-section at RHIC through muon identification from charm semileptonic decay at low transverse momentum (pT ). This can test the binary-collision scaling (Nbin) properties of the charm total cross-section and be used to study whether heavy-flavor quarks, which are used as a probe, are produced exclusively at the initial impact in hadron-h...

The effect of subcritical hadron bubbles on a first-order quark-hadron phase transition is studied. These subcritical hadron bubbles created due to thermal fluctuations introduce a finite amount of phase mixing (quark phase mixed with hadron phase) even at and above the critical temperature. For sufficiently strong transitions, as is expected to be the case for the quark-hadron transition, we s...
