We study single-hadron inclusive electroproduction in ep scattering at DESY HERA at next-to-leading order in the parton model of quantum chromodynamics endowed with non-perturbative fragmentation functions. Specifically, we consider charged-hadron production, with unspecified transverse momentum pT , in the Breit frame and D production as a function of pT , and perform comparisons with recent d...

I present a unified approach to calculating the next-to-next-to-leading order (NNLO) soft and virtual QCD corrections to cross sections for electroweak, Higgs, QCD, and SUSY processes. I derive master formulas that can be used for any of these processes in hadron-hadron and lepton-hadron collisions. The formulas are based on a unified threshold resummation formalism and can be applied to both t...

In this talk I consider dijet production at large rapidity intervals in hadron collisions and forward-jet production in DIS as candidate signatures of a BFKL evolution. The state of the art on the measurements, and on the BFKL-motivated phenomenological analyses with emphasis on the different approximations involved, is reviewed. To appear in the Proceedings of the XIIth Hadron Collider Physics...

The present status of soft hadron production in high energy heavy-ion collisions is summarized. In spite of strong evidence for extensive dynamical evolution and collective expansion of the fireball before freeze-out I argue that its chemical composition is hardly changed by hadronic final state interactions. The measured hadron yields thus reflect the primordial conditions at hadronization. Th...

This brief review of hard diffraction is focussed on the theory of the diffractive structure function F 2 . Some aspects of diffractive vector meson production and of diffractive processes in hadron-hadron collisions are also discussed.

A brief review of some topics in hadron production from heavy ion collisions is given. They include charged pion ratio as a probe nuclear symmetry energy, in-medium effects on production, en- hanced Λ c / D 0 ratio, local polarization, and X (3872) production.
