Quark coalescence based on a transport equation
Hadron spectra measured at intermediate transverse momenta, pT=2-6GeV, in 200AGeV Au-Au collisions at the Relativistic Heavy-Ion Collider (RHIC) have revealed a surprisingly large baryon-tomeson ratio ~1 and a so-called constituent quark-number scaling (CQNS) of the elliptic flow, v2(pT). Both phenomena are rather naturally explained within quark coalescence models (QCMs), where constituent qua...
متن کاملMomentum anisotropies in the quark coalescence model
Based on the quark coalescence model, we derive relations among the momentum anisotropies of mesons and baryons in relativistic heavy ion collisions from a given, but arbitrary azimuthal distribution for the partons. These relations allow us to estimate the higher-order anisotropies in the initial partonic matter from the measured hadronic anisotropies. Besides the familiar even Fourier coeffic...
متن کاملA Multi-Phase Transport model for nuclear collisions at RHIC
To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider, we have developed a multi-phase transport model that includes both initial partonic and final hadronic interactions. Specifically, the parton cascade model ZPC, which uses as input the parton distribution from the HIJING model, is extended to include the quark-gluon to hadronic matter transition and al...
متن کاملA model for multi-quark systems
As a step towards understanding multi-quark systems abundant in nature we construct a model that reproduces the binding energies of static four-quark systems. These energies have been calculated using SU(2) lattice gauge theory for a set of six different geometries representative of the general case. The model is based on ground and excited state two-body potentials and multi-quark interaction ...
متن کاملAn Improved Optimization Model for Scheduling of a Multi-Product Tree-Like Pipeline
In the petroleum supply chain, oil refined products are often delivered to distribution centers by pipelines since they provide the most reliable and economical mode of transportation over large distances. This paper addresses the optimal scheduling of a complex pipeline network with multiple branching lines. The main challenge is to find the optimal sequence and time of product injections/deli...
