Conceptually, radii are amongst the simplest Poincar\'e-invariant properties that can be associated with hadrons and light nuclei. Accurate values of these quantities necessary so one may judge character putative solutions to strong interaction problem within Standard Model. However, limiting their ability serve in this role, recent measurements new analyses older data have revealed uncertainti...

In this review, we present the current state of art our understanding spectrum excited strongly interacting particles and discuss methods that allow for a systematic model-independent calculation hadron spectrum. These are lattice QCD effective field theories. Synergies between both approaches can be exploited allowing deeper Results based on theories hadron-hadron scattering in or combinations...

Workshop presentations on elastic and diffractive scattering and other recent advances in hadron physics are summarized. The role of " factorization " in determining parton properties of the pomeron is particularly discussed.

The cross section for semi-inclusive deep inelastic scattering can be decomposed in terms of 18 structure functions. At low transverse momentum of the detected hadron, the structure functions can be expressed in terms of transverse-momentum-dependent parton distribution and fragmentation functions. Here, a few selected examples are illustrated and discussed. PACS: 13.60.-r,13.85.Ni,13.88.+e I p...

1 Abstract Lattice QCD calculation of s-wave hadron scattering lengths in the channels π-π, π-N, K-N, ¯ K-N and N-N is carried out in the quenched approximation at β = 6/g 2 = 5.7. A variant of the method of wall source is developed for this purpose, which reduces the computer time by a factor L 3 on an L 3 × T lattice compared to the conventional point source method and avoids the Fierz mixing...
