Study light scalar meson property from heavy meson decays
Cai-Dian Lu, Wei Wang
In the SU(3) symmetry limit, the ratio is equal to 1 if the scalar mesons are …
Meson spectroscopy at the Tevatron
Kai Yi
The Tevatron experiments have each accumulated about 6 \ifb good data since the start of RUN II. This large dataset provided good opportunities for meson spectroscopy studies at th…
Hadron Physics with CLAS12
Stepan Stepanyan
Hadron spectroscopy has been an essential part of the physics program with the CLAS detector in experimental Hall B at Jefferson Lab. Production of baryon and meson resonances with…
A preliminary analysis of eta' -> eta pi pi in chiral theories
Rafel Escribano
Preliminary results for the Dalitz plot distribution of decays in the frameworks of Large- Chiral Perturbation Theory and Resonance Chiral Theory are given. W…
Unitarized Chiral Perturbation Theory and the meson spectrum
Jose R. Pelaez, C. Hanhart, J. Nebreda +1
In this talk we briefly review how the unitarization of Chiral Perturbation Theory with dispersion relations can successfully describe the meson-meson scattering data and generate…
Longitudinal and Transverse Parton Momentum Distributions for Hadrons within Relativistic Constituent Quark Models
T. Frederico, E. Pace, B. Pasquini +1
Longitudinal and transverse parton distributions for pion and nucleon are calculated from hadron vertexes obtained by a study of form factors within relativistic quark models. The…
A Novel View of Exotic Hadrons and the Covariant ~U(12)-Classification Scheme
Kenji Yamada
I classify exotic hadrons into two types, "genuine" and "hidden" exotics, and propose that the "hidden" exotics would be interpreted as "chiralons" in the ~U(12)_SF times O(3,1)_L-…
Systematic Study of Two-Pion Production in NN Collisions -- from Single-Baryon to Di-Baryon Excitations
T. Skorodko, M. Bashkanov, H. Clement +5
The two-pion production in nucleon-nucleon collisions has been studied by exclusive and kinematically complete experiments from threshold up to = 1.36 GeV at CELSIUS-WASA. At…
Light-Front Quantization Approach to the Gauge-Gravity Correspondence and Hadron Spectroscopy
Guy F. de Teramond, Stanley J. Brodsky
We find a correspondence between semiclassical QCD quantized on the light-front and a dual gravity model in anti--de Sitter (AdS) space, thus providing an initial approximation to…
Charmonium molecules?
A. Valcarce, J. Vijande, T. Fernandez-Carames
In this talk we present some recent studies of multiquark components in the charmonium sector. We study the possible existence of compact four quark-states and meson-meson molecule…
Dilepton radiation by vector mesons and off-shell partons in the hot and dense medium
O. Linnyk, E. L. Bratkovskaya, W. Cassing
According to the dynamical quasiparticle model (DQPM) - matched to reproduce lattice QCD results in thermodynamic limit, - the constituents of the strongly interacting quark-gluon…
The X(3872) and other possible molecular states
P. G. Ortega, J. Segovia, D. R. Entem +1
We perform a coupled channel calculation of the and sectors in the framework of a constituent quark model. The interaction for the states is obtained using…
The phase diagram in the SU(3) Nambu-Jona-Lasinio model with 't Hooft and eight-quark interactions
J. Moreira, B. Hiller, A. A. Osipov +1
It is shown that the endpoint of the first order transition line which merges into a crossover regime in the phase diagram of the Nambu--Jona-Lasinio model, extended to include the…
Overview of nucleon structure
Gerald A. Miller
The quark-gluon properties of the nucleon are probed by a host of recent and planned experiments. These involve elastic, deep-inelastic, semi-inclusive deep-inelastic (SIDIS), and…
Dalitz Plot Analysis of B- --> D+ pi- pi-
T. M. Karbach
We present a Dalitz plot analysis of B- --> D+ pi- pi- decays, based on a sample of about 383 million Y(4S) --> BBbar decays collected by the BaBar detector at the PEP-II asymmetri…
Isospin breaking effects in the dynamical generation of the X(3872)
D. Gamermann, J. Nieves, E. Oset +1
We have studied isospin breaking effects in the X(3872) resonance and found a natural explanation for the branching fraction of the X decaying to with two and three pions bei…
Scalar, axial-vector and tensor resonances from the , interaction in the hidden gauge formalism
R. Molina, H. Nagahiro, A. Hosaka +1
We apply a unitary approach together with a set of hidden-gauge Lagrangians to study the vector-vector interaction. We study the case of the () interaction within the mo…

We study the vector-vector interaction within the framework of the hidden gauge formalism for the sector with quantum numbers charm C=0 and strangeness S=0 in the region around 400…
Structure of the lightest scalar meson from the 1/Nc expansion of Unitarized Chiral Perturbation Theory and Regge Theory
J. Ruiz de Elvira, J. R. Pelaez, M. R. Pennington +1
One-loop unitarized Chiral Perturbation Theory (UChPT) calculations, suggest a different Nc behaviour for the sigma or f_0(600) and rho(770) mesons: while the rho meson becomes nar…
Charmed mesons in nuclear matter
L. Tolos, D. Gamermann, C. Garcia-Recio +4
