The second meeting on 'New Worlds in Astroparticle Physics' reflected the growing interest and enthusiasm in the joint field of particle physics and astrophysics. The recent results of Superkamiokande on the possible neutrino oscillations are reviewed both from the experimental and theoretical points of view. The determination of the mass density in the Universe covered a wide range of topics from the Large Scale Structures to the Supernovae Cosmology project.Each main subject was introduced by a comprehensive review. The study of the origin and composition of cosmic rays is inspiring a new...

This volume covers many different subjects, from very high energy cosmic rays to neutrino physics, gravitational waves and cosmology. Recent achievements and the exciting years to come are emphasized.

The proceedings of the first meeting on “New Worlds in Astroparticle Physics” focus on the joint field of particle physics and astrophysics. This is a field widely open to both theory and experiment. Important questions of particle physics — from the role of the Higgs scalar to the deconfined QCD phase, the developments beyond the Standard Model and the subtle behavior of neutrinos — are discussed. The same is true for the relevant questions in astrophysics and cosmology — from the fluctuations in the photon background radiation to large scale structure formation, dark matter...

This volume discusses the most recent results on multiparticle production. These include the differences between quark and gluon jets from LEP at CERN, the search for the disoriented chiral condensate at Fermilab, the existence (or not) of the quark-gluon plasma and the large rapidity gaps in Hera physics. In many different experimental situations, the subject of multiparticle dynamics remains alive.Main speakers: J Antos, B J May, J D Bjorken, P Sondereger, I Tserruya, R C Hwa, R Ugoccioni, A Giovannini, C Grupen, A de Angelis, G Thompson, J Kwiecinski, B Andersson.
