Lattice approach to high-energy hadron-hadron scattering [PDF]
We discuss the non perturbative approach to the problem of high-energy hadron-hadron (dipole-dipole) scattering at low momentum transfer by means of numerical simulations in Lattice Gauge Theory.Comment: 4 pages, 5 figures, LaTeX with espcrc2.sty (v. 2.7)

Differential cross sections for high energy elastic hadron-hadron scattering in nonperturbative QCD [PDF]
Total and differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering are studied in QCD using a functional integral approach.

Factorization for short distance hadron-hadron scattering
Abstract We show that factorization holds at leading twist in the Drell-Yan cross section dσ/dQ2dy and related inclusive hadron-hadron cross sections. We review the heuristic arguments for factorization, as well as the difficulties which must be overcome in a proof.

Electromagnetic corrections to hadron-hadron scattering
Abstract We use S -matrix methods to determine the electromagnetic corrections to relativistic hadron scattering. The infrared divergences associated with soft photon emission and with the Coulomb interaction are removed to give a finite scattering amplitude which obeys crossing and has the usual analytic structure. An approximate calculation of the

On the role of longitudinal momenta in high energy hadron-hadron scattering [PDF]
Abstract We demonstrate a new method to calculate inelastic scattering cross-sections, which in contrary to the Regge-based methods takes into account the energy momentum conservation law. It is shown that the main contribution to integral expressing inelastic scattering cross-sections does not come from the multi-Regge domain.

Inclusive hadron-hadron scattering in the Feynman gauge
Abstract We analyze the structure of high-energy inclusive hadron-hadron scattering in the Feynman gauge. We show that final-state interactions cancel on a graph-by-graph basis after a sum over final states. We go on to show that the leading high-energy behavior of disconnected parton scatterings in the Feynman gauge is the same as in physical gauges,

Fixed-Angle Elastic Hadron Scattering [PDF]
The scattering amplitude in the dual model with Mandelstam analyticity and trajectory $\alpha (s)=\alpha_{0}-\gamma \ln [ (1+\beta \sqrt{s_{0} -s})/(1+ \beta \sqrt{s_{0}})]$ is studied in the limit $s,|t|\to \infty, s/t=const.$ By using the saddle point ...

The vacuum structure in QCD and hadron-hadron scattering
Standard ideas on the structure of the vacuum in QCD suggest it to be full of fluctuating color fields. We investigate the possible influence of the chromomagnetic vacuum fields on high energy hadron-hadron reactions. We suggest that high energy quarks traversing these fields will produce soft gluon and photon radiation analogous to synchrotron ...

Spin effects in high energy hadron-hadron scattering
The spin-flip amplitudes of the meson-nucleon and nucleon-nucleon scattering are calculated in the framework of the dynamic model taking into account the interactions at large distances. The consideration of the strong form factors at the corresponding vertex and prea-symptotic contributions allowed us to describe correctly the differential cross ...

About the vacuum structure in QCD and hadron-hadron scattering [PDF]
We comment on an unconventional factorization scheme which has been recently proposed by Nachtmann and Reiter. These authors propose to take into account the influence of the vacuum structure of QCD by including a correlation in spin and colour for the partons that initiate a hard scattering process.
