Prof. Fernando Navarra (USP)23/03/2015, 16:00Hadronic structure - reactions, production and decaysOral presentationWe present a short review of the theoretical and experimental status of $X(3872)$ production in high energy proton-proton and nucleus-nucleus collisions at the LHC. We then discuss the interaction of the $X(3872)$ with light mesons in a hadron gas.Go to contribution page

Dr Raphael M. Albuquerque (University of São Paulo)23/03/2015, 16:30Hadronic structure - reactions, production and decaysOral presentationWe calculate the branching ratio for the production of the meson $Y(4260)$ in the decay $B^- \to Y(4260)K^-$. We use QCD sum rules approach and we consider the $Y(4260)$ to be a mixture between charmonium and exotic tetraquark, $[\bar{c}\bar{q}][qc]$, states with $J^{PC}=1^{--}$. Using the value of the mixing angle determined previously as: $\theta=(53.0\pm0.5)^\circ$, we get the branching...Go to contribution page

Prof. Luciano Abreu (UFBA)23/03/2015, 17:30Hadronic structure - reactions, production and decaysOral presentationWe perform a field-theoretical study of possible deuteron-like molecules with both open charm and bottom, using the Heavy-Meson Effective Theory. In this approach, we analyze the parameter space of the coupling constants and discuss the formation of loosely-bound $D^{(*)} B^{(*)} $-states. We estimate their masses and other properties.Go to contribution page

Dr Ishtiaq Ahmed (UNICSUL)23/03/2015, 18:00Hadronic structure - reactions, production and decaysOral presentationIn this study, we investigate the electromagnetic form factors, $F^{em}_{X^{0^-}}$, decay constants, $f_{X^{0^-}}$, and charge radii, $\langle r_{X^{0^-}}\rangle$, where $X^{0^-}=\pi^+\text{ or }K^+$, for pion and kaon within the frame work of light-front field theory formalism using symmetric vertex function as a quark-meson interaction vertex. The above mentioned observables are evaluated...Go to contribution page

Dr Gilberto Ramalho (UFRN)23/03/2015, 18:30Hadronic structure - reactions, production and decaysOral presentationOne of the challenges of the modern physics is the description of the internal structure of the baryons and mesons. The electromagnetic structure of the nucleon $N$ and the nucleon resonances $N^\ast$ can be accessed through the $\gamma^\ast N \to N^\ast$ reactions, which deppend of the (photon) transfer momentum squared $Q^2$ [1--4]. The data associated with those transitions...Go to contribution page
