Resumen:
The LHC has pushed the scale of the needed new physics (NP) beyond the ~ TeV range. How to experimentally test NP models at and beyond those scales? A first possibility is to look for low energy remnants of such theories, like pseudo-Goldstone bosons (aka ALPs) from an approximate global symmetry. I will show how ALP masses between a few GeV and 60 GeV are poorly constrained, derive a new bound on diphoton resonances in that range, and propose new related searches at ATLAS, CMS and LHCb. A second possibility is to look for DM (much) heavier than a TeV in cosmic rays, that are observed up to 100 TeV and beyond by several ongoing and near-future telescopes (HESSII, HAWC, CTA, TAIGA, ANTARES, IceCube, KM3NeT, ...). I will discuss the theory and phenomenology of models that evade the so-called DM unitarity bound, and thus enrich the physics case of such telescopes.
