Description
I will discuss how event rates at the LHC can be compared to
reaction rates in the early Universe in a model-independent way. This
approach makes it possible to demonstrate that hidden sectors that never
reach thermal equilibrium in the early Universe are also inaccessible
for the LHC. The conclusion is that any particle that can be produced at
the LHC must either have been in thermal equilibrium with the Standard
Model at some point or must be produced via the decays of another hidden
sector particle that has been in thermal equilibrium.
