The today estimated value of dark energy can be achieved by the vacuum condensate induced by neutrino mixing phenomenon. Such a tiny value is recovered for a cut-off of the order of Planck scale and it is linked to the sub-eV neutrino mass scale. Contributions to dark energy from auxiliary fields or mechanisms are not necessary in this approach.

PAMELA was launched on June $15^{th}$ 2006 in a pressurized container on board the Russian Resurs-DK1 satellite. The satellite is flying in high inclination ($70^o$), low Earth Orbit (350-600 km), allowing measurements in various points and conditions of the geomagnetosphere. For its characteristics PAMELA is capable of addressing various items of heliospheric physics. For instance it is...

The Time-of-Flight (ToF) system is one of the key elements of the PAMELA apparatus, since it must generate the trigger for all the subdetectors and provide, alongside with the magnetic spectrometer, particle identification in the lower part of the explored energy spectrum. The ToF system will be described, with particular attention to its in-flight performances.

The Alpha Magnetic Spectrometer (AMS), to be installed on the International Space Station, will provide data on cosmic radiations in a large range of rigidity from 0.5 GV up to TV. The main physics goals in the astroparticle domain are the anti-matter and the dark matter searches. AMS offers a unique opportunity to study simultaneously SUSY dark matter in three decay channels from the...

The AMS-02 experiment is a large acceptance magnetic spectrometer to perform high statistics studies of cosmic rays on the International Space Station for more than 3 years. In this contribution, the AMS-02 expected performances in measuring the nuclear cosmic ray fluxes and their isotopic composition will be presented. AMS-02 will allow to test propagation models through the precise...

The annihilation of dark matter (DM) in the Galaxy could produce specific imprints on the spectra of antimatter species in Galactic cosmic rays, which could be detected by upcoming experiments such as PAMELA and AMS02. Recent studies show that the presence of substructures can enhance the annihilation signal by a "boost factor" that not only depends on energy, but that is intrinsically a...
