20. BPS Skyrme model and neutron stars, a two-fold approach

Mr Carlos Naya (USC)

08/09/2015, 16:20

The Skyrme model was conceived as a low energy effective field theory of strong interactions where the fundamental degrees of freedom are the pions and nuclei appear as collective excitations. In this talk, we will focus on a special case of these Skyrme theories called BPS Skyrme Model, which allows for a good description of binding energies of high nuclei. Further, here we will present two...

44. Modeling of interaction of quantum fields with extended object in the framework of Symanzik approach

Prof. Yuri Pismak (Saint-Petersburg State University)

08/09/2015, 16:40

The results obtained in the models of interaction 2-dimensional material objects with QED fields, constructed on the basis of Symanzik approach are presented. The possibility of applications of such methods for modeling the interaction of photons and electrons with hadrons and nuclei is discussed.

34. Heavy Quark Spin Symmetry and the partners of the $X(3872)$

Prof. Francisco Fernandez (Universidad de Salamanca)

08/09/2015, 17:20

The discovery of the $X(3872)$ by the Belle collaboration [1] and its confirmation by BaBar and CDF has provided the best candidate to an exotic structure in the meson sector. Because of its proximity to the $D^*D$ threshold a description of this state in terms of a $c\bar c$ state coupled to a $D^*D$ molecular structure seems to be natural. For the heavy quark sector, the spin-dependent...
