Morselli %J Physics %D 2001 %I arXiv %X The direct detection of annihilation products in cosmic rays offer an alternative way to search for dark matter particles candidates. Here we will see in particular that the study of the spectrum of antiproton and positrons offer good possibilities to perform this search and we will review our experimental effort in this direction. %U http://arxiv.org/abs/astro-ph/0103117v1
