Generalised symmetries have expanded our insight into theory but their impact has not fully translated into phenomenology yet.

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.

In this (hopefully) pedagogical talk I explain why it is useful to contemplate extra dimensions of space and how it can change the way we think about the cosmological constant problem.

Terminal velocity reached by bubble walls in cosmological first-order phase transitions is an important parameter determining both primordial gravitational wave spectrum and the production of baryon asymmetry in models of electroweak baryogenesis.

For over two decades the DAMA/LIBRA experiment has reported an annual modulation in the low-energy region consistent with the expectation from dark matter (DM) in the galactic halo due to Earth's motion around the Sun.
