Hadron scattering in two-dimensional QCD

Loop scattering in two-dimensional QCD.

Using the integrability conditions that we recently obtained in QCD 2 with massless fermions, we arrive at a sufficient number of conservation laws to be able to fix the scattering amplitudes involving a local version of the Wilson loop operator.

Hadron scattering lengths in lattice QCD.

1 Abstract Lattice QCD calculation of s-wave hadron scattering lengths in the channels π-π, π-N, K-N, ¯ K-N and N-N is carried out in the quenched approximation at β = 6/g 2 = 5.7. A variant of the method of wall source is developed for this purpose, which reduces the computer time by a factor L 3 on an L 3 × T lattice compared to the conventional point source method and avoids the Fierz mixing...

Nonperturbative QCD treatment of high-energy hadron-hadron scattering.

Total cross-sections and logarithmic slopes of the elastic scattering crosssections for different hadronic processes are calculated in the framework of the model of the stochastic vacuum. The relevant parameters of this model, a correlation length and the gluon condensate, are determined from scattering data, and found to be in very good agreement with values coming from completely different so...

High–energy Hadron–hadron (dipole–dipole) Scattering from Lattice Qcd

In this paper the problem of the high–energy hadron–hadron (dipole–dipole) scattering is approached (for the first time) from the point of view of lattice QCD, by means of Monte Carlo numerical simulations. In the first part, we give a brief review of how high– energy scattering amplitudes can be reconstructed, using a functional integral approach, in terms of certain correlation functions of t...
