After four years of data taking in space, the experiment PAMELA is showing very interesting
features in cosmic rays that might change our basic vision of their mechanisms
of production, acceleration and propagation in the galaxy. In addition, PAMELA measurements
of cosmic antimatter fluxes are setting strong constraints to the nature of Dark
Matter. In this talk PAMELA main results will be...

Cosmology and astroparticles, dark matter searches
We introduce new sum rules allowing to determine universal properties of the unknown component of the cosmic rays and show how they can be used to predict the positron fraction at energies not yet explored by current experiments and to constrain specific models.

Cosmology and astroparticles, dark matter searches
The growing observational evidence for Dark Matter from astrophysical observations gives a solid base to the Cosmological Standar Model. On the other side, the Standard Model of particles and interactions has no answer on DM nature. Experimental evidence of DM from underground experiments is under scrutiny while recent results from space experiments have no clear interpretation.

Cosmology and astroparticles, dark matter searches
Many essential paradoxes in the mechanical balance of the Galaxy are highlighted. We propose a unique and synthetic interpretation, including a cosmological theory of the origin of the observed cosmic rays, especially at the highest energies. It involves MATTER-ANTIMATTER ANNIHILATION in the median plane of the Milky Way, as a source of "DARK MATTER". We discuss the structure and balance of...
