The Italian research agency dedicated to the study of the fundamental constituents of matter and the laws that govern them, under the supervision of the Ministry of Education, Universities and Research (MIUR), is the Italian National Institute for Nuclear Physics (INFN). It conducts theoretical and experimental research in the fields of subnuclear, nuclear and astroparticle physics. Groups from the Universities of Rome, Padua, Turin, and Milan founded the INFN on 8thAugust 1951 to uphold and develop the scientific tradition established during the 1930s by Enrico Fermi and his school, with their theoretical and experimental research in nuclear physics. In the latter half of the 1950s, INFN designed and built the first Italian accelerator, the electron synchrotron developed in Frascati, where its first national laboratory was set up. During the same period, INFN began to participate in research into the construction and use of ever-more powerful accelerators being conducted by CERN, in Geneva. Today INFN employs some  6000 scientists whose work is recognized internationally not only for their contribution to various European laboratories, but also to numerous research centres worldwide. All of INFN’s research activities are undertaken within a framework of international competition, in close collaboration with Italian universities on the basis of solid academic partnerships spanning decades.

As an Institution working on cutting-edge scientific issues, INFN has a significant impact on the progress of knowledge, on technological development and on the economy of the country. Aware of this role, and of the fact that it is the duty of a public body to share its activities and the results that derive from them with society, the Institute is increasingly committed to outreach and public engagement. The Institute plays an important role in the communication of physics at the national and local level, by promoting, designing and implementing initiatives for the dissemination and promotion of scientific culture, both for the general public and for specific targets. In addition to traditional initiatives, it studies and experiments new forms of communication, emphasizing the fundamental relationship between physics and other areas of knowledge. The Institute also contributes a lot to the training of high school students through scholarships, internships, teacher training and school-work projects.

México participates in several HEP laboratories around the world: CERN, Fermilab, KEK,DESY, GSI, etc., as well as some world class experiments as HAWK, Pierre Auger Labotarory, etc.
We participates in CERN´s Master Class activities, congress, workshops and several outreach activities as: Muon Day, Women Day, "Noche de las Estrellas", among others.

Greece has a long tradition in HEP since it has been one of the founding members of CERN. HEP research is carried out in Athens (both in the National and Kapodistrian as well as in the National Technical University), Aegean, Crete, Ioannina, Thessaloniki and in the National Research Centre “Democritos”. Experimental groups from Athens, Aegean, Ioannina and Thessaloniki participate in ALICE, ATLAS and CMS experiments.
Groups from Athens, Crete and Thessaloniki have been participati

The Spanish particle physics community invests a sizable effort in science outreach and promotion. Most research institutions and universities in this field carry out numerous activities, both at local level and national level. The coordination of national activities is a responsibility of the National Center for Particle, Astroparticle and Nuclear Physics (CPAN) which centralizes and manages outreach initiatives.
Both from CPAN and from the centers themselves, there is a steady participation in all the important European events and activities such as the Science Week, the European Night of Researchers, and various IPPOG masterclasses, as well as other initiatives such as "The CPAN in High Schools” a series of seminars in high schools from which thousands of students throughout Spain benefit every year.

The particle physics community in Romania is centred around CERN collaborations, carried out by physics institutes and major universities in the country (mainly: Bucharest, Cluj, Iasi, Timisoara).
The promotion of physics, of exact sciences and communication with society are important missions of these entities.
"Particle Physics Masterclasses" is the most prestigious action we do for high school students and offers us excellent feedback.

Australia has several active particle physics groups (University of Adelaide, University of Melbourne, Monash University, University of Queensland, University of New South Wales and University of Sydney).

Members of these groups contribute to several experiments such as ATLAS, Belle/Belle II, COMET, Ice Cube, LHCb along with various direct dark matter searches, and are working towards the realisation of future facilities (CEPC, EIC, FCC, ILC). There is also a vibrant theory community with members throughout the country providing input to their experimental colleagues and working on theoretical understandings and expansions of the Standard Model.

In France, introducing young people and the general public to basic science (nuclear physics, physics of elementary particles, cosmology and astrophysics), the technological advances they require and their related applications (energy, health, etc.), is a key mission for the 25 CNRS/IN2P3 national research laboratories and platforms, and the CEA/IRFU. Our educational and outreach activities are carried out in close collaboration to teaching staff and take many forms: visit to laboratories, “Masterclass” discovery days, teacher-training courses, loans of cosmic-ray detectors for use in classrooms, teaching aids, exhibitions, websites, virtual visits, audiovisual productions, books, etc.

Our goal: to give people a taste for science and physics

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.
