The Hadron’s structure Properties of hadrons are only determined to a small degree by the constituent quarks. Quarks and gluons dynamics plays a fundamental role in the definitions of hadron’s properties: mass, spin, etc… Generalized Parton Distributions (GPDs) contain both the usual form factors and structure functions, but in addition they include correlations between states of different longitudinal and transverse momenta. GPDs give a three-dimensional picture of the nucleon. Nucleon Form Factors have been mainly studied using electromagnetic probes, but the physical diagrams can be inverted… and a complementary approach can be used In a similar way Deeply Virtual Compton Scattering (DVCS) can be crossed-studied non-perturbative QCD Paola Gianotti – INFN perturbative QCD 35 306

Other approaches String theory is today a candidate for a quantum theory of gravity.

Other approaches String theory is today a candidate for a quantum theory of gravity. Nevertheless, string theory was introduced in an attempt to describe the large number of mesons and hadrons that were experimentally discovered in the 1960’s. The idea was to view all these particles as di�erent oscillation modes of a string. It was later discovered that hadrons and mesons are actually made of quarks and that they are described by QCD. Recently, there has been remarkable progress in the study of the strong coupling dynamics of gauge theories by employing duality between gauge theory and string theory. Initiated by the discovery of the Ad. S/CFT correspondence intensive attempts to apply the idea of the gauge/string duality to QCD has been made. (EPJA 35: 81 (2008), PRL 96, 201601 (2006), Phys. Rept. 323: 183, (2000)) A better understanding of QCD could help in developing this theory courtesy of S. Brodsky & G. de Teramond Paola Gianotti – INFN 10

Hadron’s masses The elementary particles of the Standard Model gain their mass through the Higgs mechanism. However, only a few percent of the mass of the proton is due to the Higgs mechanism. The rest is created in an unknown way by the strong interaction. Glueballs would be massless without the strong interaction and their predicted masses arise solely from the strong interaction. The possibility to study a whole spectrum of glueballs might therefore be the key of understanding the mechanism of mass creation by the strong interaction. C. Morningstar and M. Peardon, Phys. Rev.

The role of Chiral Symmetry u and d quarks have very small and similar

The role of Chiral Symmetry u and d quarks have very small and similar masses, this seems to indicate that the equations of QCD possess some additional symmetry, Chiral Symmetry, that is spontaneously broken. this mechanism is playing an important role in the process of mass generation. In the nuclear medium (ρ>0) we can restore this symmetry at least partially. Hints of this effect have been already observed. We wants to extend these studies to charmed mesons.
