Messina (Italy)

Giorgio Giardina (CT), Giuseppe Mandaglio (CT), Graziano Venanzoni (LNF), Simon Eidelman (Budker Institute of Nuclear Physics)

The Symposium will focus on the new projects and new lines of researches in the field of the Lepton and Hadron Physics that will be developed in the main Laboratories and Research Centres during the next 10 years. Therefore, the Symposium is open to contributions on various kinds of particle physics (also of astrophysical interest). In the Symposium, the main emphasis will be on the discussion (from experimental and theoretical points of view) of high precision measurements and calculation useful to test the Standard Models, searches of new particles and interaction forces (dark force and dark matter), resonances by hadronic or electromagnetic interactions and their decay into scalar and vector mesons.

10 The experiment PANDA: physics goals and experimental setup

PANDA is an experiment that will run at FAIR, the new accellerator facility in Darmstadt, Germany, in 2018. A high intensity antiproton beam with up to 15 GeV/c momentum will collide on a fixed target (pellet or jet target). The experiment will investigate a wide range of physics topics in the hadronic interactions in the non-perturbative QCD regime (center of mass energies between 2 and 5.5 GeV). The apparatus used to achieve these physics goals will be outlined in this talk.

Relatore: Dr. Gianluigi Boca (University of Pavia)

11 eta and eta' Physics at MAMI

The A2 collaboration studies photoproduction mechanisms and decays of light mesons. The photon beam used, is produced through Bremsstrahlung of electrons in a thin radiator. The electrons are delivered by the MAMI accelerator with a maximum energy of E_e = 1604 MeV. Post-radiating electrons are momentum-analysed in the Glasgow-tagging spectrometer. In 2012, a new tagging spectrometer was successfully installed to cover the accessible eta'-photoproduction range. The target is located in the centre of the Crystal Ball-spectrometer. Forward angles are covered by a spectrometer-wall consisting of TAPS-crystals. The experimental set-up described above is ideal for high-precision experiments on light pseudoscalar mesons in a clean production environment. Results from the Crystal Ball-experiment are competitive with other world-leading facilities. Especially results from neutral decays measured with the Crystal Ball are of exceptional precision. In this presentation, the capabilities for the production of light mesons with the Crystal Ball set-up at MAMI will be described. Furthermore, recent results from eta and eta' decays will be presented. Among these are the recent determination of the eta' cross-section near threshold with unprecedented accuracy, and a new determination of the eta transition form factor from the eta->e+e-g decay. At the end an outlook on future measurements will be given.

17 Interpretation of the X(3872) as a charmonium state plus an extra component due to the coupling to the meson-meson continuum

Relatore: Elena Santopinto (INFN)

18 Exotic Hadron Spectroscopy

Since ten years experiments have been observing a host of exotic states decaying into heavy quarkonia. The interpretation of most of them still remains uncertain and, in some cases, controversial, notwithstanding a considerable progress has been made on the quality of the experimental information available and a number of ideas and models have been put forward to explain the observations. In this talk we will expose the state-of-the-art of exotic spectroscopy, and will review the most promising theoretical interpretations, in particular we will discuss the nature of Zc(3900), a charged charmonium-like state recently discovered at BES and Belle. Finally, we will propose a new mechanism to explain the prompt X(3872) production cross section at hadron colliders.
