This year, IPPOG took part in EPS-HEP 2025, the flagship European conference in high energy physics, held in Marseille, France. Organised by several major French research institutes (CPPM, CC-IN2P3, CPT, L2IT, LAM, and LUPM), EPS-HEP 2025 brought together hundreds of physicists from across the globe to present and discuss the latest developments in particle physics, astroparticle physics, neutrino physics, outreach, and related fields.

As part of its ongoing mission to foster engagement, education, and communication in particle physics, IPPOG contributed to the event with a poster presentation by Fabiola Cacciatore (IPPOG Scientific Secretary and Communication Officer) titled Masterclass for Non-Scientific CERN Staff. The poster highlighted the initiative that brings the unique experience of the International Masterclasses (typically reserved for high school students) to the many CERN staff members working outside the scientific departments. The initiative is a celebration of inclusivity and recognition, reinforcing that everyone at CERN is part of the larger mission of discovery and understanding, regardless of their background.

In addition to the poster, several members of the IPPOG Forum were actively involved in the scientific programme. Kate Shaw (ATLAS forum) delivered a powerful plenary talk on science outreach, education, and equity in physics. Notably, Shaw was also the recipient of the EPS Outreach Prize in 2015, underlining her long-standing contribution to the field (read more here). This marks the second time that EPS-HEP has featured a plenary talk dedicated to outreach, following Anna Godinho’s (former CERN Representative) talk in Hamburg in 2023, a clear sign that the importance of communication and public engagement is gaining well-deserved visibility in major physics conferences.

A dedicated parallel session on education and outreach was also part of the conference programme, allowing for deeper discussion among educators, researchers, and outreach professionals. The session featured presentations on a range of topics—from inclusive teaching approaches to international collaboration models—demonstrating how outreach continues to evolve in both content and practice.

This year’s EPS Outreach Prize was awarded to Beamline for Schools (BL4S), a long-standing partner of IPPOG. Run by CERN, BL4S offers high school students the unique opportunity to propose and carry out real experiments at research facilities such as CERN and DESY. Since its launch in 2014, the programme has engaged thousands of young people from around the world, fostering hands-on experience with particle physics and building global enthusiasm for fundamental research. The prize recognises BL4S’s innovative model for science engagement and its lasting educational impact.
