Jet Fragmentation via Recombination of Parton Showers
Kyong Chol Han, Rainer J. Fries, Che Ming Ko
We propose to model hadronization of parton showers in QCD jets through a hybrid approach involving quark recombination and string fragmentation. This is achieved by allowing gluon…
Jet Fragmentation via Recombination of Parton Showers
Kyong Chol Han, Rainer J Fries, Che Ming Ko
We study hadron production in jets by applying quark recombination to jet shower partons. With the jet showers obtained from PYTHIA and augmented by additional non-perturbative eff…
Charmonium production from nonequilibrium charm and anticharm quarks in quark-gluon plasma
Taesoo Song, Kyong Chol Han, Che Ming Ko
Parameterizing the charm and anticharm quark momentum distributions by the Tsallis distribution, we study the nonequilibrium effect on the charmonium production rate in a quark-glu…
Bottomonia suppression in heavy-ion collisions
Taesoo Song, Kyong Chol Han, Che Ming Ko
Using the two-component model that includes both initial production from nucleon-nucleon hard scattering and regeneration from produced quark-gluon plasma (QGP), we study the effec…
Charmonium production in heavy-ion collisions from SPS to LHC
Taesoo Song, Kyong Chol Han, Che Ming Ko
Using the two-component model that includes charmonium production from initial nucleon-nucleon hard scattering and regeneration in the produced quark-gluon plasma, we study p…
Dilepton production in a schematic causal viscous hydrodynamics
Taesoo Song, Kyong Chol Han, Che Ming Ko
Assuming that in the hot dense matter produced in relativistic heavy-ion collisions, the energy density, entropy density, and pressure as well as the azimuthal and space-time rapid…
