Dark photons arising at or below the GeV scale from a spontaneously broken gauge symmetry are one of the simplest and most exciting extensions of the Standard Model.

The next major goal of the Large Hadron Collider (LHC) program is to explore the shape of the Higgs potential by measuring the trilinear Higgs self-coupling.

Understanding the emergence of spacetime from quantum mechanics is a theoretical question of fundamental importance. Implicit in the AdS/CFT correspondence and more generally in the holographic principle.

In a curved spacetime the definition of particles depends on the observer's frame of reference.

The majority of known hadrons in the low-energy QCD spectrum are resonances observed in multi-particle scattering processes.

Continuous spin particles (CSPs) arise naturally in the classification of unitarity representations of the Poincaré group but have long been dismissed because of their unintuitive nature.
