PARTONS: PARtonic Tomography Of Nucleon Software [PDF]
We describe the architecture and functionalities of a C++ software framework, coined PARTONS, dedicated to the phenomenology of Generalized Parton Distributions.

I discuss our current understanding of parton distributions. I begin with the underlying theoretical framework, and the way in which different data sets constrain different partons, highlighting recent developments. The methods of examining the uncertainties on the distributions and those physical quantities dependent on them is analyzed.

MRST partons and uncertainties. [PDF]
We discuss uncertainties in the extraction of parton distributions from global analyses of DIS and related data. We present conservative sets of partons, at both NLO and NNLO, which are stable to x,Q2,W2 cuts on the data. We give the corresponding values

PARTONIC INTERPRETATION OF GENERALIZED PARTON DISTRIBUTIONS [PDF]
Dispersion relations have been applied to hard exclusive processes suggesting that generalized parton distributions can be fully determined from their values on a kinematical ridge. We show significant pitfalls associated that vitiate this approach. We suggest an improved treatment of this assumption.

Parton Correlations in Double Parton Scattering [PDF]
Double parton scattering events are directly sensitive to the correlations between two partons inside a proton and can answer fundamental questions on the connections between the proton constituents. In this chapter, the different types of possible correlations, our present knowledge of them, and the processes where they are likely to be important, are

Soft radiation in parton-parton scattering
Abstract We investigate the pattern of soft gluon radiation associated with parton-parton scattering by explicit evaluation of the 2 → 3 scattering processes in the soft limit. After azimuthal averaging, the results provide the initial conditions for an angular-ordering approximation to coherent multiple soft gluon emission, which may be incorporated

On the Shape of Nucleons at High Energies
A scenario of the evolution of the shape of nucleons with increasing energy is described in the framework of an extended parton model, which consistently takes into account the transverse motion of the partons.
