Quark confinement in Buchmüller’s picture of a rotating flux tube is reconsidered in the context of a minimum area evaluation of the Wilson loop. The question is asked whether resulting spin independent dynamics are consistent with Thomas precessional spin dependence leading from electric confinement. The answer appears to be in the negative; self-consistency of the picture found in the literat...

The intermittency analysis of single event data (particle moments) in multiparticle production is improved, taking into account corrections due to the reconstruction of history of a particle cascade. This approach is tested within the framework of the α-model. ∗e-mail: [email protected], [email protected]

An isospin analysis of B → ππ decays yields sin 2α, where α is the usual CKM angle α ≡ arg[−V td V * tb /(V ud V * ub)] without hadronic uncertainty if isospin is a perfect symmetry. Yet isospin symmetry is broken not only by electroweak effects but also by the u and d quark mass difference — the latter drives π 0 − η, η ′ mixing and converts the isospin-perfect triangle relation between the B ...
