In July, particle physicists in the US completed the Snowmass process\u2014a decadal community planning exercise that forges a vision of scientific priorities and future facilities. Organized by the Division of Particles and Fields of the American Physical Society, this year\u2019s Snowmass meetings considered a range of plans including neutrino experiments and muon colliders. One new idea that generated buzz was the Cool Copper Collider (or C3<\/sup> for short). This proposal calls for accelerating particles with conventional, or \u201cnormal-conducting,\u201d radio frequency (RF) cavities\u2014as opposed to the superconducting RF cavities used in modern colliders. This \u201cretro\u201d design could potentially achieve 500 GeV collision energies with an 8-km-long linear collider, making it significantly smaller and presumably less expensive than a comparable superconducting design.<\/p>\n

The goal of the C3<\/sup> project would be to operate as a Higgs factory, which\u2014in particle-physics parlance\u2014is a collider that smashes together electrons and their antimatter partners, called positrons, at energies above 250 GeV. Such a facility would make loads of Higgs bosons with less of the mess that comes from smashing protons and antiprotons together\u2014as is done at the Large Hadron Collider (LHC) in Switzerland. A Higgs factory would give more precise measurements than the LHC of the couplings between Higgs bosons and other particles, potentially uncovering small discrepancies that could lead to new theories of particle physics. \u201cI think the Higgs is the most interesting particle that\u2019s out there,\u201d says Emilio Nanni from the SLAC National Accelerator Laboratory in California. \u201cAnd we should absolutely build a machine that\u2019s dedicated to studying it with as much precision as possible.\u201d<\/p>\n

But an outsider might wonder why another Higgs-factory proposal is being added to the particle-physics menu. A similar factory design\u2014the International Linear Collider (ILC)\u2014has been in the works for years, but that project is presently stalled, as the Japanese government has not yet confirmed its support for building the facility in Japan. Waiting in the wings are several other large particle-physics proposals, including CERN\u2019s Future Circular Collider and China\u2019s Circular Electron Positron Collider.<\/p>\n","protected":false},"excerpt":{"rendered":"
