Things that are large enough to be seen in experiments and things that are too small. At the edge between these two worlds operates the Large Hadron Collider (LHC, in CERN, Geneva).

Particles behave according to the rules of quantum mechanics and special relativity, unified in the mathematical structure of Quantum Field Theory (QFT). The Standard Model (SM), is a QFT that explains incredibly well the outcome of all terrestrial experiments, from measurements of electron properties to the Higgs boson discovery.

Yet, we know there are things we do not know, in the sense that can not be explained by the SM, such as Dark Matter or Quantum Gravity, and possibly lurk at smaller distance.

So we can ask two questions.

First we can ask how can Nature be at smaller distances? We can use QFT to immagine different worlds, where the Higgs boson is composite, where every SM particle has a partner (Supersymmetry), where the graviton is massive, where spacetime has extra-dimensions...

Then we ask how we can test these hypotheses and we design experiments to be performed at the LHC or other facilities. For instance, to test if the Higgs boson is a composite particle, like the proton, we measure its interactions in search of substructure.
