- th / 0 61 01 28 v 1 3 1 O ct 2 00 6 Factorization for hadronic heavy quarkonium production ⋆

We briefly review several models of heavy quarkonium production in hadronic collisions, and discuss the status of QCD factorization for these production models.

We present an overview of dynamic and related models for pion electroproduction on the nucleon due to ∆(1232) excitation. The electromagnetic multipoles and their ratios obtained from these models and from effective field theories are compared, and the existing contradictory results for the pion cloud effects are discussed.

Using a multiphase transport model (AMPT) with both partonic and hadronic interactions, we study the multiplicity and transverse momentum distributions of charged particles such as pions, kaons and protons in central Au+Au collisions at RHIC energies. Effects due to nuclear shadowing and jet quenching on these observables are also studied. We further show preliminary results on the production o...

The in-medium modification of nucleon-nucleon (NN) cross sections is investigated by means of particle production in heavy ion collisions (HIC) at intermediate energies. In particular, the density dependence of the inelastic cross sections considerably affects the pion and kaon yields and their rapidity distributions. However, the (π/π)and (K/K)-ratios depend only moderately on the in-medium be...
