High-energy quark-quark scattering and the eikonal approximation
The high–energy quark–quark scattering amplitude is calculated first in the case of scalar QCD, using Fradkin’s approach to derive the scalar quark propagator in an external gluon field and computing it in the eikonal approximation. The results are then extended to the case of “real” (i.e., fermion) QCD. The high–energy quark–quark scattering amplitude turns out to be described by the expectati...
متن کاملValidity of the Eikonal Approximation*
We summarize results on the reliability of the eikonal approximation in obtaining the high energy behavior of a two particle forward scattering amplitude. Reliability depends on the spin of the exchanged field. For scalar fields the eikonal fails at eighth order in perturbation theory, when it misses the leading behavior of the exchange-type diagrams. In a vector theory the eikonal gets the exc...

متن کاملOn the Eikonal Approximation in AdS Space
We explore the eikonal approximation to graviton exchange in AdS5 space, as relevant to scattering in gauge theories. We restrict ourselves to the regime where conformal invariance of the dual gauge theory holds, and to large ’t Hooft coupling where the computation involves pure gravity. We give a heuristic argument, a direct loop computation, and a shock wave derivation. The scalar propagator ...
متن کاملA Test of the Eikonal Approximation in High–energy (e,e ′ P) Scattering
The Glauber method is extensively used to describe the motion of a hadronic projectile in interaction with the surrounding nuclear medium. One of the main approximations consists in the linearization of the wave equation for the interacting particle. We have studied the consequences of such an assumption in the case of the 12 C(e, e ′ p) 11 B * reaction at high proton momenta by comparing the r...
