چکیده
The large-Nc limit of the meson-baryon effective Lagrangian is shown to reduce to a semiclassical field theory. A chiral bag structure emerges naturally in the Nc → ∞ limit. A possible connection between the chiral bag picture and the Skyrme model is discussed. The classical meson-baryon theory is used to reproduce the M π non-analytic correction to the baryon mass obtained previously as a loop correction in chiral perturbation theory.

The talk is an introduction into diquark condensation phenomena which occur in QCD at high energy density. They are driven by instantons and instanton-antiinstanton pairs (or " molecules "), which generate attraction in some qq channels. A number of phases is possible, with or without restoration of chiral symmetry: the work is not finished and we do not yet know which take place in real QCD. W...

The decay of Λ b → Σ (*) c πl¯ ν processes are calculated in the framework of heavy baryon chiral perturbation theory with help of the 1/N c expansion. The decay rate distributions over v · v ′ where v and v ′ are the 4-vector velocities of Λ b and Σ (*) c respectively, and over the pion and lepton energies are given. The decay branching ratios amount to about 1.21(0.971)% for Λ b → Σ c πl¯ ν a...

We discuss the formation of sand d-wave baryon resonances as predicted by the chiral SU(3) symmetry of QCD. Based on the leading order term of the chiral Lagrangian a rich spectrum of molecules is generated, owing to final-state interactions. The spectrum of sand d-wave baryon states with zero and non-zero charm is remarkably consistent with the empirical pattern. In particular, the recently an...

We review the spectroscopy and some properties of hadrons containing two charmed quarks, or more generally, two heavy quarks. This includes heavy baryons such as (bcu), and possible exotic multiquark states.

Results presented at the DIS97 workshop by the H1, ZEUS and E665 collaborations on processes yielding large rapidity gaps and energetic leading baryons are reviewed. A consistent picture begins to emerge in which diffractive processes dominate when the fractional longitudinal momentum loss at the baryon vertex x IP is small, with substantial contributions from other processes as x IP increases....
