HEP Seminar-The Cool Copper Collider: An Advanced Concept for a Future e+e- Higgs Factory

A lepton-collider Higgs factory, to precisely measure the couplings of the Higgs boson to other particles, followed by a higher energy run to measure the Higgs self-coupling, is widely recognized as a primary focus of modern particle physics. In this talk, we will present the study of a new concept for a high gradient, high power accelerator with beam characteristics suitable to study the Higgs boson, the Cool Copper Collider (C3), with the goal of minimizing the capital and operating costs. C3 is based on the latest advances in rf accelerator technology and utilizes optimized cavity geometries, novel rf distribution, and operation at cryogenic temperatures to allow the linear accelerator to achieve high accelerating gradients while maintaining the overall system efficiency. We will present the latest demonstrated performance of prototype accelerators and highlight the future development path for C3.
