Spin Effects in Large Transverse Momentum Exclusive Scattering Processes

Nucleon-nucleon scattering at large momentum transfer is analyzed within the framework of quantum chromodynamic quark and gluon interactions. The spin dependence of the hadronic amplitude is found to be particularly sensitive to the underlying dynamical mechanisms. Detailed discussions of the quark interchange and Landshoff pinch singularity contributions are given for large angle pp, np and pi...

Membrane Scattering with M-Momentum Transfer

Membrane scattering in m(atrix) theory is related to dynamics in three-dimensional SU(2) gauge theory, with transfer of p11 being an instanton process. We calculate the instanton amplitude and find precise agreement with the amplitude in eleven dimensional supergravity.

Transverse Momentum Broadening Due to the Multiple Scattering

Most high energy collisions can be described by a single hard scattering. By studying the single scattering, we can extract the parton distribution functions and test the short-distance dynamics of strong interactions. The normal parton distributions have the interpretation of the probability distributions to find a parton within a hadron. On the other hand, in order to study quantum correlatio...

Transverse Momentum Transfer and Low x Parton Dynamics at HERA

The transverse momentum transfer correlation is introduced as a sensitive probe that can be used to discrimate between models for parton dynamics in low-x deep-inelastic scattering. Expectations for uncorrelated models and models with short-range or long-range correlations are discussed and confronted to results obtained from the Lepto and Ariadne Monte Carlo simulation programmes.

Transverse Spin / Transverse Momentum Analogy and Gauge Invariance of Deeply Virtual Compton Scattering

Using the similarity between twist 3 contributions to transverse spin for usual parton distributions and transverse momentum for non-diagonal parton distributions, we determine for the simple case of a scalar (pion, He) target the linear in transverse momentum twist-3 contribution to Deeply Virtual Compton amplitude. This allows to write a gauge invariant amplitude for this non-forward process.
