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 …
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-…
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…
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…
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…
The Y(3940), Z(3930) and the X(4160) as dynamically generated resonances from the vector-vector interaction
R. Molina, E. Oset
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…
J/ψand Upsilon at high temperature
I. M. Narodetskii, Yu. A. Simonov, A. I. Veselov
We use the screened Coulomb potential with -dependent coupling constant and the non--perturbative quark--antiquark potential derived within Field Correlator Method (FCM) to calc…
