ar X iv : a st ro - p h / 02 04 01 7 v 1 1 A pr 2 00 2 CMB and Cosmological Parameters : Current Status and Prospects .

The last years have been an exciting period for the field of the Cosmic Microwave Background (CMB) research. With recent CMB balloon-borne and ground-based experiments we are entering a new era of ’precision’ cosmology that enables us to use the CMB anisotropy measurements to constrain the cosmological parameters and test new theoretical scenarios.

We address a class of models in which neutrinos, having a small mass, originate the highest energy cosmic rays interacting with the relic cosmic neutrino background. Assuming lepton number symmetry and an enhanced neutrino

Quantum-gravity effects may introduce relevant consequences for the propagation and interaction of high energy cosmic rays particles. Assuming the space-time foamy structure results in an intrinsic uncertainty of energy and momentum of particles, we show how low energy (under GZK) observations can provide strong constraints on the role of the fluctuating space-time structure.
