Snowmass Accelerator Frontier

The decadal Particle Physics Community Planning Exercise known as “Snowmass” is in the final

stages. Snowmass is a scientific study to define the most important questions for the field of

particle physics and identify promising opportunities to address them. The Snowmass report

will serve as input for the Particle Physics Project Prioritization Panel (P5) and develop a

strategic plan for U.S. particle physics that will guide the field for the next decade. The

Snowmass process was initially announced at the April 2020 APS meeting but was delayed for a

year due to the COVID-19 pandemic. The delay in no way stifled the imagination and creativity

of the particle physics community and a plethora of ideas are now on the table. The technical

maturity of the proposed facilities ranges from shovel ready to those that are still largely

conceptual. This talk will give an overview of some of the collider options; status, technical

readiness level and challenges that we expect to see coming out of this first stage of the

planning process.
