Hadron correlations from recombination

Hadron Correlations from Recombination and Fragmentation

We review the formalism of quark recombination applied to the hadronization of a quark gluon plasma. Evidence in favor of the quark recombination model is outlined. Recent work on parton correlations, leading to detectable correlations between hadrons, is discussed. Hot spots from completely quenched jets are a likely source of such correlations which appear to be jet-like. It will be discussed...

Hadron Correlations and Parton Recombination

Parton recombination has been found to be an extremely useful model to understand hadron production at the Relativistic Heavy Ion Collider. It is particularly important to explore its connections with hard processes. This article reviews some of the aspects of the quark recombination model and places particular emphasis on hadron correlations.

Hadron Correlations in Jets and Ridges through Parton Recombination

Hadron correlations in jets, ridges and opposite dijets at all pT above 2 GeV/c are discussed. Since abundant data are available from RHIC at intermediate pT , a reliable hadronization scheme at that pT range is necessary in order to relate the semihard partonic processes to the observables. The recombination model is therefore first reviewed for that purpose. Final-state interaction is shown t...

High Pt hadron-hadron correlations

We propose the formulation of a dihadron fragmentation function in terms of parton matrix elements. Under the collinear factorization approximation and facilitated by the cut-vertex technique, the two hadron inclusive cross section at leading order (LO) in e+ eannihilation is shown to factorize into a short distance parton cross section and the long distance dihadron fragmentation function. We ...
