Studies of hadronic final states of e + e − annihilations at LEP are reviewed. The topics included cover hadronic event shapes, measurements of αs, determinations of QCD colour factors and tests of the non-Abelian gauge structure of QCD, differences between quark and gluon jets, QCD with heavy quarks and selected results of two-photon scattering processes.

Using three point QCD sum rules method, the form factors relevant to the semileptonic Bs → DsJ(2460)lν decay are calculated. The q2 dependences of these form factors are evaluated and compared with the heavy quark effective theory predictions. The dependence of the asymmetry parameter α, characterizing the polarization ofDsJ meson, on q2 is studied. The branching ratio of this decay is also est...

We give character formulae for the positive energy unitary irreducible representations of the N-extended D=4 conformal superalgebras su(2,2/N). Using these we also derive decompositions of long superfields as they descend to the unitarity threshold. These results are also applicable to irreps of the complex Lie superalgebras sl(4/N). Our derivations use results from the representation theory of...
