Hadronic Spectral Function and Charm Meson Production

Charm Meson Production from Meson-nucleon Scattering

Because of their large masses, one expects charm mesons to be mostly produced in the initial preequilibrium stage of relativistic heavy ion collisions. They have thus been suggested as possible probes of the initial dynamics in these collisions. Previous studies have been concentrated on the production of charm quarks from the preequilibrium partonic matter [1]. For charm meson production from ...

Hadronic Charm Production in Qcd

We consider how a cc pair produced in a hadronic collision may be converted into either a cc bound state or a pair of charmed particles. The fact that many other quarks are present leads us to doubt a naive application of duality to the charm sector alone. The possibility of charmed quark combination with other already existing quarks makes straightforward calculations of the charm production c...

SyStematics of Charm Production in Hadronic Collisions

On Hadronic Production of the Bc Meson

Two of the approaches to the hadronic productions of the double heavy mesons Bc and B ∗ c are investigated. Comparison in various aspects on the results obtained by the approaches is made and shown in figures and a table. Some trial understanding of the approaches themselves and the achieved results is presented. The results may be used as some references for discovering the mesons at Tevatron ...

Measurement of Neutral Meson Production in Hadronic

The 7°r, qj, and w meson productions have been studied using 3 million hadronic Z events recorded with L3 detector at LEP. The meson production in the final sample, two-jet and three-jet event samples as well as in each jet have been measured and compared with the JETSET and HERWIG Monte Carlo predictions. The momentum distributions are measured and compared with Monte Carlo prediction and anal...
