Effective scientific communication and public outreach are essential components of modern high-energy physics research, serving to educate the public, engage stakeholders, and ensure continued support for fundamental science.
This article presents a comprehensive analysis of the communication and outreach strategies implemented by the Compact Muon Solenoid (CMS) experiment at CERN, one of the flagship experiments at the Large Hadron Collider (LHC).
The CMS communications program demonstrates how large-scale scientific collaborations can effectively reach diverse audiences through multi-platform engagement, educational initiatives, and innovative digital content creation.
