The many flavours of HEMT

The physics of eight flavours

When the flavour content of QCD is increased sufficiently, the theory develops a non-trivial infra red fixed point. Thus, for a number of flavours above a certain critical value, but not yet so high that asymptotic freedom is lost, QCD becomes a conformal field theory. The location of the lower limit of this conformal window has not yet been unequivocally determined. Using an improved lattice a...

Heavy Flavours: Experimental Summary

Production and hadronisation of heavy quarks is one of the most attractive laboratories for QCD prediction tests. There is an active interplay between experimental analyses and theoretical developments in this area. The aim of the working group was to discuss the relevant experimental and theoretical results which become available or updated after the previous DIS workshop. The theoretical talk...

Inclusive Decays of Heavy Flavours

Recent progress in the theoretical description of inclusive heavy flavour decays is reviewed. After an outline of the theoretical methods applications to total decay rates and semileptonic decay spectra are presented. Contribution to the workshop on “Heavy Quark Physics”, December 13 – 16, 1994, Bad Honnef, Germany. TTP 95–06 March 1995

Strong Interactions of Light Flavours

After an introduction to chiral perturbation theory, the effective field theory of the standard model at low energies, a brief overview is given of applications to lightflavour physics. Three topics in the strong interactions of pseudoscalar mesons are then discussed in some detail: loops and chiral logs, pion-pion scattering and isospin violation. Lectures given at the Advanced School on QCD 2...
