A second workshop on small x physics, within the Small x Collaboration, was held in Lund in June 2002 with the aim of over-viewing recent theoretical progress in this area and summarizing theâ€¦ (More)

The dislocation relaxation between 100 K and 200 K (IkHz) in plastically deformed niobium, formerly named "a-relaxation" is a hydrogen Snoek-Koster relaxation (cold work relaxation). This is shown byâ€¦ (More)

We introduce an explicit form of the multi-instanton weight including also instantonâ€“ anti-instanton interactions for arbitrary Nc in the two-dimensional CP Ncâˆ’1 model. To that end, we use theâ€¦ (More)

We compute in the instanton vacuum the nucleon matrix elements of the twistâ€“4 QCD operators describing power corrections to the second moments of the unpolar-ized structure functions, F L and F 2.â€¦ (More)

We present a quantitative analysis of the electromagnetic pion form factor in the light-cone sum rule approach, including radiative corrections and higher-twist effects. The comparison to theâ€¦ (More)

Charged current events are studied at HERA with polarized beams, using a Monte Carlo event generator and taking into account detector smearing effects. The observed asymmetries are used to study theâ€¦ (More)

We analyze power corrections to flavour singlet deep inelastic scattering structure functions in the framework of the infrared renormalon model. Our calculations, together with previous results forâ€¦ (More)

We review the possibility to use the renormalons emerging in the perturbation series of the twist-2 part of the nonsinglet structure functions F L , F 2 , F 3 , and g 1 to make approximateâ€¦ (More)

In this paper hadroproduction of charmonium states in polarized pp collisions is discussed. A thermal picture for the gluonic cloud of comovers is given making contact between the formalism and theâ€¦ (More)

We review the possibility to use the renormalons emerging in the perturbation series of the twist-2 part of the nonsinglet structure functions F L , F 2 , F 3 , and g 1 to make approximateâ€¦ (More)
