MesonNet Meeting

29 Sept 2014, 09:00 → 1 Oct 2014, 14:30 Europe/Rome

Auditorium B. Touschek (INFN - Laboratori Nazionali <!--ID_UTENTE=503--> di Frascati)

Andrzej Kupsc (Uppsala University), Simona Giovannella (LNF)

MesonNet is a research network within EU HadronPhysics3 project. The main objective is the coordination of light meson studies at different European accelerator research facilities: COSY (Jülich), DAPHNE (Frascati), ELSA (Bonn), GSI (Darmstadt) and MAMI (Mainz). The network includes also EU researchers carrying out experiments at VEPP-2000 (BINP), CEBAF (JLAB) and heavy flavor-factories (Babar, Belle II, BESIII experiments). The scope are processes involving lightest neutral mesons: π0, η, ω, η', φ and the lightest scalar resonances. The emphasis is on meson decay studies but we include also meson production processes and meson baryon interactions. The majority of the participants of the network are experimentalists while close collaboration with theory groups is essential for the planning of experiments and the interpretation of the data.
The scientific program will include a Poster Session. Maximun poster size is ISO paper size A0, i.e. 841 by 1,189 millimetres (33.1x46.8 in.).
The registration desk will open at 8:30.
