چکیده
It is shown that the parity–violating deep–inelastic scatterings of unpolarized charged leptons on polarized protons, ℓ ∓ + P → (−) ν ℓ +X, could provide a sensitive test for the behavior and magnitude of the polarized strange–quark density in a proton. Below charm threshold these processes are also helpful to uniquely determine the magnitude of individual polarized parton distributions.

Integrability of the Wess–Zumino–Witten model as a non–ultralocal theory * Abstract We consider the 2–dimensional Wess–Zumino–Witten (WZW) model in the canon-ical formalism introduced in [5]. Using an r–s matrix approach to non–ultralocal field theories we find the Poisson algebra of monodromy matrices and of conserved quantities with a new, non–

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];...
