چکیده
I briefly review three topics of recent interest concerning power corrections, renor-malons and Sudakov resummation: (a) 1/Q corrections to event shape observables in e + e − annihilation, (b) power corrections in Drell-Yan production and (c) facto-rial divergences that arise in resummation of large infrared (Sudakov) logarithms in moment or 'real' space.

This is a quick review of CP non-conservation in B physics. Several methods are described for testing the Kobayashi-Maskawa single phase origin of CP violation in B decays, pointing out some limitations due to hadronic uncertainties. A few characteristic signatures of new physics in B decay asymmetries are listed. Invited talk given at the 1999 Chicago Conference on Kaon Physics Chicago, IL, Ju...

An introduction to some outstanding issues in QCD is presented, with emphasis on work by Diakonov and co-workers on the influence of the instanton vacuum on low-energy QCD observables. This includes the calculation of input valence-parton distributions for deep-inelastic scattering.
