N = 1 Supergravity Models with Vanishing Cosmological ConstantWe consider N = 1 matter-coupled supergravity theories which exhibit positive semidefinite scalar potentials, yielding to a naturally vanishing cosmological constant. Different examples of supergravity models having this property are discussed and their main features pointed out.

Monte Carlo Renormalization Group Methods and Results in QCDThe way quantum field theory is defined and working beyond perturbation theory — this is the main topic of these lectures. The first part is a general introduction to renormalization group ideas, while the specific methods and results are discussed in the second part.

Proton DecayPerhaps one should begin with the historical survey of the subject. However, there recently appeared two, one theoretical. and one experimental., excellent reviews. Hence, I shall restrict myself to the motivations why we are seriously working on proton decay experiment.

The Glueballs of QCD and BeyondIt has been generally believed that the characteristics of hadronic interactions obey local gauge invariance of the nonabelian group SU(3). and are subject to color confinement. This leads to QCD. without quarks, in which the gluons — the eight gauge bosons of SU(3). are massless, carry color charge and have spin = 1.

New Flavours: How They can be Looked for at the (p̄) Collider with the Lepton Asymmetry AnalyserOur knowledge on the basic structure of matter appears at present to be in terms of quarks and leptons. They can be classified as “uplike” and “downlike” states according to their electric charge, which is fractional for quarks and integer for leptons.
