I will discuss the mass reach for electroweakinos at future hadron colliders in several
split SUSY scenarios and I will show that collider searches and direct detection experiments
have the potential to cover large part of the parameter space. I will then review the zero
and finite temperature properties of the QCD axion: despite non-perturbative QCD, axion
properties can be extracted at the percent level partially exploiting the foreseen experimental
accuracy in case of discovery. Finally, I will discuss the impact on dark matter and cosmology.
