The nine Networking Activities cover all of the most important issues in hadron physics: from the structure of the nucleon to the characteristics of the quark-gluon plasma, from theĀ  possible existence of new bound hadronic and nuclear states to novel computational techniques. They all promote collaborations between a larger number of expert groups in Europe, very often between theoreticians and experimentalists, and are closely related to the activities of the Research Infrastructures in HadronPhysics3. They foster a culture of co-operation between the participants in the project, and those scientific communities that benefit from these Research Infrastructure. This is particularly relevant for the development and maintenance of common databases needed for the analysis of experimental data and the computation of theoretical quantities; feasibility studies of new instrumentation, methods and technologies; promotion of coordinated activities of similar experiments; and the dissemination of knowledge through scientific publications and the organisation of workshops.

Objectives

  • To grant an efficient and accountable way of managing the project through effective management and decision-making structures, while retaining a high level of representation and transparency, both with regard o the scientific and the financial aspects.
  • To carry out, on behalf of the beneficiaries, the specific coordination tasks laid down in the Grant Agreement (GA) with the Commission, covering all scientific, technical, organizational and financial aspects.

The THURIC network will concentrate on the following three topics:

  • The properties of the plasma before hadronisation and how the phase transition toward the hadronic world takes place.
  • The modification of hard probes due to the quark gluon plasma through which they pass and the information the hard probes carry about this interaction.
  • A detailed study of the initial thermalisation.

Study the feasibility of an electron-nucleon collider (ENC) as a future extension of the HESR at the FAIR facility.

The main objective of the MesonNet network is the coordination of light meson studies at different European accelerator research facilities: COSY (Juelich), DAPHNE (Frascati), ELSA (Bonn), GSI (Darmstadt) and MAMI (Mainz). The network includes EU researchers carrying out experiments at VEPP-2000 (BINP), CEBAF (JLAB) and B-factories (Babar, Belle, Belle II experiments): these facilities are also included in the network.

The program of SPHERE consists of four activities:

  • Physics (PHY): close collaboration between various theory groups and experimentalists to define the goals of future experiments and to focus on the most relevant physics issues. Weak decays of hypernuclei and the production of various exotic hypernuclei (hypernuclei with extreme isospin, multiple strangeness or charm) are major topics.
  • Experiments (EXP): hypernuclear experiments planning and analysis and interpretation of experimental results require detailed input from very different branches of physics, ranging from high energy nuclear reactions, atomic transitions in hyperatoms, nuclear capture, nuclear physics up to hadron physics.
  • Detectors (DET): exchange of know-how to design, to build, to integrate and to operate the new experimental equipments and develop analysis tools.
  • Theory (THE): this activity will serve to join efforts of the various theory groups with the common goal to develop theoretical models appropriate for the analysis of hypernuclear production and structure data, including large-scale numerical simulations.

The experiments PANDA (Antiproton Annihilation at Darmstadt) and CBM (Compressed Baryonic Matter) at FAIR will be devoted to studies on the nature of QCD pursuing complementary approaches: PANDA will investigate the properties of the strong force at the quark level, whereas CBM will explore the properties of strongly interacting matter under extreme conditions.
The network FAIRnet aims to develop:

  • Joint R&D on software and hardware to satisfy requirements common to PANDA and CBM

Both experiments will be operated at very high reaction rates (up to 10 MHz) which calls for unprecedented detector performance in terms of readout speed and radiation hardness.
In addition, a required software tools for simulations and data analysis are practically indentical.

The network for the heavy flavoured probes of deconfined QCD matter formed in heavy ion collisions at relativistic energies has the following objectives:

  • To improve and encourage interaction between theorists and experimentalist for the interpretation of the new LHC results on heavy flavoured observables and electroweak boson in heavy ion collisions.
  • To support young researchers working on this novel field of heavy flavour production in heavy ion collisions.
  • To ensure an effective scientific transition from LHC to FAIR future facility.
  • To support the soft diffractive community in nucleus-nucleus collisions.

The central objectives of the proposed networking activity LEANNIS are the definition and coordination of studies on low-energy antikaon nucleon (nucleus) interaction in theory and experiment centered in Europe, but with strong impact on the worldwide strategy in the field.

  • Lattice QCD calculations in the low-energy regime

Lattice QCD currently provides the only ab initio method for performing QCD calculations in the low-energy regime, and for acquiring a quantitative description of the physics of hadrons and nuclear forces with controlled systematic errors. To reliably connect hadron physics with QCD, extreme computing resources are required.
To make efficient use of the current investment in supercomputers, and to further advance high performance computing in Europe, a unified programming environment and the pooling of resources, both human and computational, are needed.
