Constraining strong baryon–dark-matter interactions with primordial nucleosynthesis and cosmic rays

Underground laboratories, shielded by the Earth's crust from the particles that rain down on the surface in the form of cosmic rays, provide the low radioactive background environment necessary to host key experiments in the field of particle and astroparticle physics, nuclear astrophysics and other disciplines that can profit of their characteristics and of their infrastructures. The cosmic silence condition existing in these laboratories allows the search for extremely rare phenomena and the exploration of the highest energy scales that cannot be reached with accelerators. Major fundamental challenges are within the scope of these laboratories, notably, understanding the properties of neutrinos and dark matter, and exploring the unification of the fundamental forces of nature. I will review the physics reach and briefly describe the main underground facilities that are presently in operation around the world.

Dark Matter Search

The direct detection of annihilation products in cosmic rays offers an alternative way to search for supersymmetric dark matter particles candidates. The study of the spectrum of gamma-rays, antiprotons and positrons offers good possibilities to perform this search in a significant portion of the Minimal Supersymmetric Standard Model parameters space. In particular the EGRET team have seen a convincing signal for a strong excess of emission from the galactic center that have not easily explanation with standard processes. We will review the achievable limits with the experiment GLAST taking into accounts the LEP results and we will compare this method with the antiproton and positrons experiments, the direct underground detection and with future experiments at LHC.

Different Origin

In the framework of hypercolor extension of the Standard Model we consider cosmic rays scattering off hidden mass candidates. Specifically, there are two components of the Dark Matter in this model having close masses but different origin. As a result, neutrino production in the processes of scattering ofhigh energy electrons on these DM candidates is substantially different, and the secondary neutrino canbe seen, in principle, at neutrino detectors. We also note other interesting aspects of these type reactions.
