چکیده
The recent progress in our understanding of heavy-flavour decays allows us to define more reliably which future measurements on charm decays are needed to further advance our understanding of QCD and to get our theoretical tools ready for treating beauty decays. After sketching the theoretical landscape I list those required measurements. I argue that some – in particular those concerning inclusive semileptonic charm decays and their lepton spectra – can presumably be performed only at a tau-charm factory.

QCD suggests that gluons in the nucleon play an important role in so-called " the proton spin problem ". In this talk, the behavior of the polarized gluon distribution in the nucleon is discussed by using the positivity condition of distribution functions together with the unpolarized and polarized experimental data.

We investigate the effects of photon radiation on deep-inelastic eγ scattering. Depending on the set of variables chosen, we find appreciable effects in the kinematic region accessible at LEP2. Convenient analytic results for O(α) corrected differential cross sections are presented. CERN-TH/95-233 August 1995 E-mail address: [email protected] E-mail address: [email protected]

These lectures introduce some of the basic notions of effective field theories, as used in particle physics. The topics discussed are the ∆S = 1 and ∆S = 2 weak interactions, and chiral perturbation theory as applied to mesons, baryons, and hadrons containing heavy quarks.

We describe three different methods for generating quasi-exactly solvable potentials, for which a finite number of eigenstates are analytically known. The three methods are respectively based on (i) a polynomial ansatz for wave functions; (ii) point canonical transformations; (iii) supersymmetric quantum mechanics. The methods are rather general and give considerably richer results than those a...
