The Deep Underground Neutrino Experiment (DUNE) is a leading-edge, international experiment for neutrino science. Discoveries over the past half-century have put neutrinos, the most abundant matter particles in the universe, in the spotlight for further research into several fundamental questions about the nature of matter and the evolution of the universe — questions that DUNE will seek to answer.

Georgia is a country in the South Caucasus region, located at the crossroads of Eastern Europe and Western Asia. It has a long tradition of education, science, and engineering, with strong emphasis on mathematics and natural sciences in its academic culture. Over recent decades, Georgia has increasingly focused on internationalization in higher education and research, strengthening its engagement with European and global scientific institutions.

Within the framework of CERN IPPOG, Georgia contributes to international efforts aimed at promoting particle physics education and public outreach. Georgian universities and research institutions actively support initiatives that enhance scientific literacy, encourage student participation in STEM fields, and integrate modern physics topics into educational programs.

Georgia’s collaboration with CERN and IPPOG reflects a broader national commitment to research-based education, capacity building, and the dissemination of fundamental science. Outreach activities focus on engaging teachers, students, and the general public through lectures, workshops, and educational events, fostering interest in particle physics and related technologies.

Through its participation in IPPOG, Georgia strengthens international cooperation, shares best practices in science education, and supports the development of a new generation of scientists and engineers, contributing to the global particle physics community while advancing national educational and research priorities.

Particle physics outreach in Portugal is mainly pursued by LIP, the Laboratory for Instrumentation and Experimental Particle Physics. LIP is a nation-wide research institute with 3 nodes associated with the universities of Lisbon, Coimbra and Minho, and connections to other universities. It covers areas of experimental physics, collaborating in particle and astroparticle experiments at CERN and around the world, radiation detectors and technological developments for particle physics, and their application to societal issues. LIP also collaborates with theoretical groups around the country.

KM3NeT, the Cubic Kilometre Neutrino Telescope, is one of the most ambitious neutrino observatories ever built, designed to explore the universe from the depths of the Mediterranean Sea. The infrastructure consists of two main sites: ARCA (Astroparticle Research with Cosmics in the Abyss), off the coast of Sicily, dedicated to the search for high-energy astrophysical neutrinos, and ORCA (Oscillations Research with Cosmics in the Abyss), near Toulon in France, which focuses on low-energy neutrinos for studying neutrino oscillations and mass ordering. The detectors are built in the form of giant arrays of ultrasensitive light sensors (the photomultipliers, PMTs) arranged into multi-sensors optical modules of novel design.

Altogether the PMTs allow to detect the faint light emitted, through the Cherenkov effect, when relativistic charged particles cross the detector. The immense instrumented volume, combined with the clarity of deep seawater, allows KM3NeT to act as a three-dimensional telescope with an excellent view of the Southern sky, complementing other neutrino observatories across the globe. In addition, KM3NeT offers unique opportunities for Earth and sea sciences: the continuous monitoring of environmental and oceanographic parameters turns the experiment into a permanent deep-sea laboratory, generating valuable high-bandwidth, real-time data for multiple scientific disciplines.

Slovenia has been involved with various big particle physics projects almost as long as it has been a country. Indeed, the first collaboration agreement between CERN and Slovenia dates back to the same year (1991). However, Slovenian physicists were already involved with various particle physics experiments before that time. Nowadays, Slovenian scientific institutions collaborate with the ATLAS experiment at CERN, experiments Belle and Belle II at KEK, and observatory Pierre Auger. Slovenian physicists also organise various Masterclasses, science shows, talks and open days for high-school students, as well as co-coordinate Slovenian Teacher Programmes in connection with CERN.

The CMS (Compact Muon Solenoid) experiment is one of the two large, general-purpose particle physics detectors at CERN's Large Hadron Collider (LHC) . It's a major international scientific collaboration, involving over 6000 particle physicists, engineers, and technicians from across the globe . The CMS Collaboration unites members of the particle physics community in a quest to advance humanity's knowledge, using data collected by the CMS detector to answer questions related to particle physics

In Ireland, promoting curiosity, creativity and critical thinking through fundamental physics is an important part of our scientific and educational mission. The Irish particle physics and cosmology community is actively engaged in introducing students, teachers and the wider public to the wonders of the Universe - from the smallest building blocks of matter to the evolution of the cosmos.

Outreach and education activities are coordinated through universities, research institutes, and collaborative national efforts, with support from organisations such as the Dublin Institute for Advanced Studies (DIAS), Research Ireland, and the Irish Centre for High-End Computing (ICHEC). These activities include school visits, physics Masterclasses, public lectures, science festivals, exhibitions, online resources, and engagement with teachers through professional development workshops.

Ireland has joined CERN in 2025, marking a new era of participation in international scientific discovery and collaboration. As part of this momentum, we aim to inspire the next generation of scientists and engineers, promote scientific literacy, and foster an appreciation for the role of fundamental research in society.

Our goal: to make particle physics accessible, engaging, and meaningful to all.

The UK has a diverse and substantial portfolio of particle physics research and outreach activities. UK physicists collaborate and conduct research in projects all over the world and within the UK. These activities include the ATLAS, CMS, LHCb, and ALICE experiments at the Large Hadron Collider, experiments studying the nature of the neutrino such as DUNE, T2K/HyperK, MicroBooNE, SoLiD and SNO+, experiments dedicated to the search for dark matter such as LZ, DarkSide, ADMX and AION, experiments at the intensity frontier such as Mu2e, g-2, Mu3e, and NA62, and robust initiatives in accelerator development, future detector instrumentation, and theoretical research. The UK boasts a vibrant culture of public engagement embedded in individual institutions and spanning experimental research programmes. This includes a national programme of schools masterclasses, and multiple initiatives making use of scientific data from experiments in educational and outreach activities. UK physicists and public engagement professionals regularly organise and contribute to public events at the institutional and national level, and develop online resources, smartphone applications, posters/booklets, and contribute to teacher training and to publications on educational and public engagement pedagogy. The UK hosts successful public engagement collaborations with artists across a range of visual and performing arts. A particular focus of the UK public engagement strategy is in reaching audiences with low science capital or in geographically remote areas. Examples include leadership of the Physics Without Frontiers programme and the development of an award-winning innovative programme to enable visually impaired audiences to engage with particle and accelerator physics.
