We numerically study the effects of high gluon density at small x on the evolution of gluon distribution function in both hadrons and nuclei. Using a newly derived, Wilson renormalization group-based evolution equation which includes n to 1 gluon ladder fusion, we find significant reduction in nuclear gluon distribution function for large nuclei at zero impact parameter at energies relevant for...

The assumption of angular ordering in gluon radiation is essential to obtain quantitative results concerning gluonic behaviors. In order to prove the validity of this assumption, we have applied our momentum space flux-tube formalism to check out the angular dependences of gluon radiation. We have calculated the probability amplitudes to get new gluon, and have found that the new gluon is gener...

Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q(q̄)g → gq(q̄) and the inelastic qq̄ ↔ gg scatterings are evaluated in the lowest order in QCD. Including both jet energy loss and conversions in the expanding quark-gluon plasma produced in relativistic heavy ion collisions, we ha...

Continuum and lattice analyses have revealed the existence of a mass-scale in gluon two-point Schwinger function. It has long been conjectured that this expresses action mechanism for gauge boson mass generation quantum chromodynamics (QCD). For such to be true, it is necessary sufficient dynamically-generated, massless, colour-carrying, scalar gluon+gluon correlation emerges as feature dressed...

We calculate the linear and circular polarization of gluons produced in conjunction with massive quarks in the annihilation process e+e− → qq̄G. The linear polarization is calculated in the hadron event plane as well as in the gluon-beam plane. Beam polarization and polar orientation effects are included in our discussion. For typical top pair production energies at the Next-Linear-Collider (NLC...
