Near-integrability and confinement for high-energy hadron-hadron collisions
We investigate an effective Hamiltonian for QCD at large s, in which longitudinal gauge degrees of freedom are suppressed, but not eliminated. In an axial gauge the effective field theory is a set of coupled (1 + 1)dimensional principal-chiral models, which are completely integrable. The confinement problem is solvable in this context, and we find the longitudinal and transverse string tensions...
متن کاملThermal hadron production in high energy collisions
It is shown that hadron abundances in high energy ee, pp and pp̄ collisions, calculated by assuming that particles originate in hadron gas fireballs at thermal and partial chemical equilibrium, are in very good agreement with the data. The freeze-out temperature of the hadron gas fireballs turns out to be nearly constant over a large center of mass energy range and not dependent on the initial c...
متن کاملInelastic diffraction and color-singlet gluon-clusters in high-energy hadron-hadron and lepton-hadron collisions
It is proposed, that “the colorless objects” which manifest themselves in largerapidity-gap events are color-singlet gluon-clusters due to self-organized criticality, and that optical-geometrical concepts and methods are useful in examing the spacetime properties of such objects. A simple analytical expression for the t-dependence of the inelastic single diffractive cross section dσ/dt (t is th...
متن کاملDiffraction and colorless gluon-clusters in high-energy hadron-hadron and lepton-hadron collisions
The role played by colorless gluon-clusters in the optical-geometrical approach to high-energy inelastic diffractive scattering is discussed. A simple analytical expression for the t-dependence of the integrated single diffractive cross section (t is the four-momentum transfer squared) is derived. Comparison with the existing data and predictions for future experiments are presented. ∗e-mail ad...
متن کاملHigh pT hadron spectra in high-energy heavy-ion collisions
We calculate the hadron spectra in high-energy pp, pA and AA collisions within a pQCD parton model. Analyses of experimental data show that the modification of the spectra in pA and AA as compared to that in pp collisions is consistent with multiple parton scattering scenario and is dictated by the transition from absorptive soft interaction at low pT to incoherent hard parton scattering at hig...
