An introduction to the methods and ideas of Chiral Perturbation Theory is presented in this talk. The discussion is illustrated with some phenomenological predictions that can be compared with available experimental results.

A brief sketch is made of the present observational status of neutrino properties, with emphasis on the hints from solar and atmospheric neutrinos, as well as cosmological data on the amplitude of primordial density fluctuations. Implications of neutrino mass in particle accelerators, astrophysics and cosmology are discussed. Invited talk at TAUP95, Toledo, September 1995. [email protected];...

We review the present status of polarized structure functions measured in deep-inelastic scattering. We discuss the x and Q 2 dependence of the structure function g 1 , and how it can be used to test perturbative QCD at next-to-leading order and beyond. We summarize the current knowledge of polarized parton distributions, in particular the determination of the first moment of the quark and gluo...

The perturbative QCD predictions concerning deep inelastic scattering at low x are summarized. The theoretical framework based on the leading log 1/x re-summation and k t factorization theorem is described and some recent developments concerning the BFKL equation and its generalization are discussed. The QCD expectations concerning the small x behaviour of the spin dependent structure function ...
