The Gluon Distribution in Hadrons

We consider the effects of hadron size and quark composition on the distribution of gluons in mesons and baryons. Coherence effects in the color singlet bound state eliminate the usual quark-mass infrared singularity. The color cancellations are important for all x gluon unless the gluon transverse momentum is large compared to the inverse hadron size. Using a simple model for the meson bound s...

Analyticity and Quark-Gluon Structure of Hadrons

The amplitudes of hadron-hadron forward elastic scattering at high energy are investigated on the basis of analiticity and crossing-symmetry which is valid in QCD. The universal uniformizing variable for them is proposed and the formulae for crossing-even and crossing-odd amplitudes are derived. The same parameters in these formulae determine the real and imaginary (total cross sections) parts ...

Observing Quark-gluon Plasma with Strange Hadrons

We review the methods and results obtained in an analysis of the experimental heavy ion collision research program at nuclear beam energy of 160–200A GeV. We study strange, and more generally, hadronic particle production experimental data. We discuss present expectations concerning how these observables will perform at other collision energies. We also present the dynamical theory of strangene...

Gluon Density in Nuclei

In this talk we present our detail study ( theory and numbers ) [1] on the shadowing corrections to the gluon structure functions for nuclei. Starting from rather contraversial information on the nucleon structure function which is originated by the recent HERA data, we develop the Glauber approach for the gluon density in a nucleus based on Mueller formula [3] and estimate the value of the sha...

Evidence for color fluctuations in hadrons from coherent nuclear diffraction.

A QCD-based treatment of projectile size fluctuations is used to compute inelastic diffractive cross sections σdiff for coherent hadron-nuclear processes. We find that fluctuations near the average size give the major contribution to the cross section with ≤ few% contribution from small size configurations. The computed values of σdiff are consistent with the limited available data. The importa...
