Though essentially equivalent at the present time to the constraints from the diffuse $\\gamma$-ray background, they allow a widely independent approach and they should improve sensibly in the nearby future. We discuss the resulting constraints on inflationary parameters using a Broken Scale Invariance (BSI) model as a concrete example. Commentaires: 10 pages, 3 figures |
