No unexpected particles were observed in the first 15 years of data-taking at the Large Hadron Collider (LHC), the highest energy accelerator on Earth—a disappointment stated by many physicists throughout the Snowmass process, and reflecting a view that has also been expressed outside of the Snowmass meetings. Although LHC will continue to run with modest upgrades, this lack of discovery leaves no clear focus for the next decade of high energy searches, and may also point to a “nightmare-scenario” where the Standard Model that forms the present basis of particle physics is complete up to the Planck scale (an energy level far beyond the ability of any conceivable experiment to probe) and particle physics “wheeze[s] to its end.”
