  2. Hadron physics aims at understanding the properties of hadrons and their mutual interactions from QCD (the theory governing the dynamics of quarks, the constituents of hadrons). This is an ambitious goal and the field is compartmented into several subfields that basically study the phases and structures of QCD at their various levels of complexity.

  3. EXPERIMENTS BNL, RHIC Jlab MiniBooNE, Minerna BaBar, CLEO KEK JPARC T2K BELLE, BES DaFne-Frascati MAMI-Mainz, ELSA-Bonn HADES COMPASS COSY-JÜLICH GSI-FAIR . . . Typical topics in hadron physics: Chiral Perturbation Theory Effective Field Theory Baryon Resonance Structure and Quark ModelsExotic HadronsHadron Properties from Lattice QCDSpectroscopy of light and heavy quark hadronsQuarkoniaGlueballs, hybrids and multiquarksHadrons in matterHeavy ion collisions . . .

  4. The spanish theory groups have been and are very active in contributing to the progress of Hadron physics. The groups are well integrated in the international circuit, participating in the big european projects (e.g. HadronPhysics) and providing support to the ongoing and future experiments, with an especial focus to the FAIR physics program. The experimental groups working on hadron physics projects are very limited. However, many spanish citizens are involved in experimental collaborations (MAINZ, GSI, CERN, …) and could be the seed for an eventual growing of the experimental groups. Activity integrated in

UCM contribution: development and extension of a realistic relativistic modeling of the reaction, incorporating it into the MC tool and making possible the data analysis ratio ofGE/GM form factors in bound nucleons, Data from JLAB and MAMI, FSI are constrained by induced polarization measurement Data suggests the pressence of mild medium modifications of the form factors, like the ones implied in QMC model Several publications co-authored with the Hall A collaboration of JLAB, about polarization transfer in the 4He((e,e 'p)3H reaction, PRL106, (2011) 052501, PRL 105, 072001 (2010), PRL 91, 052301   (2003)

  27. HADRON SPECTROSCOPY: Quark Models versus Dynamical models Quark Models: Mesons = Baryons = Valencia, Salamanca Dynamical Models: Mesons = Baryons = generated from unitary (non-perturbative) extensions of chiral perturbation theory in coupled channels Barcelona, Granada, Murcia, Valencia  As a result, it is found that some of the observed resonances are generated dynamically through the multiple scattering of meson-meson (or baryon-meson) pairs in coupled channels. Their properties might be very different from the Quark Model predictions.

  28. Theconstituent quark model

  29. Quark Models: Many of the observed resonances fall within the quark model predictions A. Valcarce, H. Garcilazo, F. Fernández and P. González, Rept. Prog. Phys. 68, 965 (2005)‏ The quark model also predicts other baryon properties. Form factors, decay widths of simple and doubly heavy hadrons, C. Albertus, E. Hernández, J. Nieves, Phys. Rev. D85 (2012) 084035; Phys. Lett. B704 (2011) 499, etc… But… some anomalies:

  31. Several groups are extending their models to thecharmdegree of freedom to interpret the data from BELLE, BABAR, BES, CLEO … but also in preparation for the forthcoming experiments atFAIR that will be sensitive to the in-medium properties of hadrons with charm. Valencia  dynamically generated open charm and hidden charm Barcelona meson resonances from meson-meson coupled channel dynamics UB, UAB dynamically generated charmed baryon resonances within Gröningen a SU(4) model  D-meson properties in hot and dense medium Granada  dynamically generated charmed baryon resonances within UAB a SU(8) model (accounts for heavy-quark spin symmetry)‏ Valencia Salamanca quark model charmed baryon and meson resonances

  37. Isospin violations in X(3872) decays… Because of the mass differences D0 D-and D*0 D*-the kinetic energy (including the mass terms) does not conmute with isospin, the X(3872) is an admixture of isospin I=0 and I=1 (r is the DD* relative distance in the molecule X) neu: D0 D*0 + ccand ch: D+D*- + cc(neutral and charged thresholds differ in 8 MeV) Assuming a contact interaction ….
