About HFCC

The HFCC, originally named the Higgs Factory Coordination Consortium, was created by DOE and NSF in 2024 to provide strategic direction and leadership for the U.S. community to engage, shape, and thereby advance the development of the Physics, Experiments, and Detectors (PED) and the Accelerator (A) program for a potential future Higgs Factory; and to ensure cooperation with our partners in the international program. 

In September 2025, the HFCC was renamed to the Higgs Factory Circulator Collider to explicitly support the FCC-ee; the charge for the HFCC remains the same.

The HFCC is led by Higgs Factory Steering Groups: HFSC-PED & HFSC-A.  The full charge for the HFCC-PED is located here while the charge for the HFSC-A is located here; the structure of the two charges is quite similar.  A summary of the charge follows:

• Physics and technical feasibility studies, including any associated design and R&D efforts, to advance detector concepts and accelerator designs for a future e+/e- Higgs factory;
• Prioritization and stewardship of the national R&D efforts;
• Development of the pre-project R&D scope that will be required to initiate a project;
• Conceptualization of the software and computing for the experiments and accelerator;
• Develop various funding models that will be required to support the R&D efforts;
• Ensure collaborations by the U.S. with our partners are cost-effectively carried out to advance the future Higgs factory initiatives.
