Bienvenue WelcomeWillkommenBenvenutoBienvenidoto the STRONG-2020 website

STRONG-2020 “The strong interaction at the frontier of knowledge: fundamental research and applications” has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 824093.

Objectives of the project

The strong interaction is one of the cornerstones of the Standard Model (SM) of particle physics, and its experimental and theoretical study attracts an active community of about 2500 researchers in Europe.

The list of fundamental open questions at the frontier of our current knowledge in the strong interaction is very rich and varied including a full understanding of (i) the partonic structure of hadrons, (ii) exotic hadronic states, properties of (iii) dense quark matter and of (iv) hot and dense quark-gluon plasma, as well as (v) precision tests of the SM. Such research topics are studied experimentally and theoretically mostly via particle collisions at low (a few tens of GeV) and high (up to 14 TeV) energies. Associated developments in state-of-the-art detectors/data-acquisition/beams/targets are required, as well as in theoretical (lattice, effective field, perturbative) calculations.

The STRONG-2020 project brings together many of the leading research groups and infrastructures involved today in the study of the strong interaction in Europe, and also exploits the innovation potential in applied research through the development of detector systems with applications beyond fundamental physics, e.g. for medical imaging and information technology. The Consortium includes 46 participant institutions, embracing 14 EU Member States, one International EU Interest Organization (CERN), and one EU candidate country. Together with host institutions of 21 other countries, without EU funds benefits, the project involves research in 36 countries. The project is structured in 32 Work Packages (WP): 7 Transnational Access Activities (TA), 2 Virtual Access Activities (VA), 7 Networking Activities (NA) and 14 Joint Research Activities (JRA). Furthermore, 2 WPs take care, respectively, of the “Management and Coordination” of the project and of “Communication and Outreach".

Statement on the aggression of Russian Federation against Ukraine

Image
The STRONG-2020 Community firmly condemns military aggression by Russia against Ukraine, and the violation of international law by the Russian Federation.
Our Community represents a project deeply rooted in Europe, and we are strongly concerned about these dramatic events.
Our thoughts are going to our Ukrainian colleagues, and we express our sincere solidarity with the entire Ukrainian population.
The STRONG-2020 project will follow the instructions and measures issued by the E.U. Commission, which details can be found on the Commission’s official site: https://ec.europa.eu/commission/presscorner/detail/en/IP_22_1544
We also express our support to Russian scientists who reject this invasion.
From its very beginning, the core of our project is to bring leading research groups and infrastructures together, and promote non-military application of its results.
We will continue to embrace and promote scientific collaboration as a peace driver in Europe.

MANAGEMENT AND DISSEMINATION

MAN-Project Management and Coordination

The complexity of the STRONG-2020 Integrating Activity requires specific management structures and a dedicated highly-skilled team. MAN takes in charge the effective management, the steering of the whole project and the monitoring of the progress of all Work Packages including the planned scientific activities, industrial developments and applications as well as society issues. The management team ensures the contractual and administrative implementation. It will oversee the use of resources and prepare Periodic and Final Reports.

DISCO-Dissemination and Communication

The main aim of the DISCO WP is to promote and realize efficient and targeted dissemination, exploitation of results and communication activities resulting from the dedicated research and transnational activities performed within the project, in order to raise the awareness about their importance, to promptly inform the various communities on the obtained results and to enhance the future financing opportunities targeting the self-sustainability of the involved community, with special care on sex and gender dimension. DISCO is a transversal and integrated activity, which involves all the other WPs of the project. The objective is to promote and realize dissemination and communication of the results coming from the project, with special focus on the involved research infrastructures, toward: - The scientific community of specialists in hadron physics: aiming to present the main results coming from the project activities, the research infrastructures dedicated to the strong interaction studies and the working opportunities both within the researchers community involved in the project, inter-WPs, contributing to cross-fertilization and birth of new ideas, as well as to those researchers who are not directly involved in the project in order to look for new collaborations and scientific opportunities. - The wider scientific community: aiming to present the main results coming from the project activities and the research infrastructures to those researchers who are not directly involved in research in strong interaction physics. - The general public, industry representatives and policy makers: aiming to present the main results coming from the project activities and the research infrastructures to the general public, policy makers, industry representatives, students, children, to raise the awareness about this type of research and related infrastructures, to promote a new generation of scientists and enhance future financing opportunities
