Low-mass physics in a high-energy world

• Andre Frankenthal (University of California Irvine (US))

The LHC was designed to achieve the highest proton-proton collision energies ever, enabling the exploration of some of the heaviest particles in the Standard Model and beyond. However, with great ingenuity and clever ideas, the various LHC experiments have also advanced an impressive low-mass physics program. This is no small feat, as low-mass signals are challenging to tease out amid the vast amount of data produced in proton collisions and the inherent experimental constraints that result. In this talk, I will give a broad overview of the techniques that have significantly enhanced our sensitivity to low-mass physics at the LHC. Additionally, I will discuss results from various experiments that highlight this progress and explore intriguing future possibilities in this region of phase space, particularly in the context of searches for complex dark matter models with enriched internal dynamics.
