The set of quantum Boltzmann equations relevant for leptogenesis is derived using non-equilibrium quantum field theory. They manifest memory effects leading to a time-dependent CP asymmetry which depends upon the previous history of the system. This result is particularly relevant in resonant leptogenesis where the asymmetry is generated by the decays of nearly mass-degenerate right-handed...

I will discuss how the seesaw mechanism is realized in the heterotic string as well as its phenomenological implications.

The measurement of the energy spectrum above $2.5\cdot 10^{18}$ eV at the Pierre Auger Observatory is presented. Above 20000 events of zenith angle less than $60^\circ$ have been recorded by the surface detector and the acceptance of 7000 km$^2$sr yr, achieved during the construction phase is larger than of previous experiments. The spectral features of the particle flux will be disscused....

We present the first results about the studies of UHECR arrival directions using the first data collected at the Pierre Auger Observatory (the present data set corresponds to ~ 1 year
of acquisition of the complete southern array).
We discuss in particular the analysis of large-scale patterns in the sky distribution of cosmic rays and the search for a correlation between the arrival...

The DM-TPC is an optical readout time projection chamber being developed by groups from Boston University, Brandeis University and MIT to search for dark matter. The device has the capability of measuring the properties of tracks of low energy particles, including ionization rate, true 2-dimensional projections on the readout plane with resolutions of the order of 100 microns, and the...

The NEMO3 experiment is designed for the search of neutrinoless double beta decay. Located in the Laboratoire Souterrain de Modane (Modane Underground Laboratory), the detector accomodates 10 kg of double beta emitters, including about 7 kg of 100Mo and 1 kg of 82Se. The NEMO3 detector also allows to perform the measurement of the half-life of two-neutrino double beta decay for 7 isotopes. No...
