Examination of the H dibaryon within a chiral constituent quark model

We perform a coupled--channel calculation of the H dibaryon within a chiral constituent quark model. The problem is solved within a quark model constrained by the experimental data of strangeness --1 and --2 two--baryon systems. We examine in detail the role played by the different contributions of the interacting potential as well as the number of coupled channels considered. Special attention has been payed to the parameter dependence, flavor symmetry breaking and spatial configurations. The value extracted for the binding energy of the H dibaryon, being compatible with the restrictions imposed by the Nagara event, falls within a plausible extrapolation of recent lattice QCD results.Comment: 14 pages, 13 figure

Optimización de una cimentación pilotada y de la superestructura de un centro comercial mediante simulación de la interacción terreno-estructura en suelos licuefactables con un caso de sismo dimensionante : análisis comparativo de los resultados con y sin interacción terreno estructura

Congreso celebrado en la Escuela de Arquitectura de la Universidad de Sevilla desde el 24 hasta el 26 de junio de 2015.Soil-structure interaction techniques have been widely written about and largely used in the Energy domain, even if they are still not commonly used among Civil Engineers. Nevertheless, these techniques have been introduced in the latest versions of earthquake codes and their use can lead to large optimizations. The aim of this article is to show a practical methodology to take into account soil-structure interaction in seismic design applied to buildings through a real case where structural optimizations lead to savings valued in 17.5 M€. The structural study is done using a classical modal - spectral seismic analysis completed with the addition of dynamic impedances that reproduce soil structure interaction. This approach accurately incorporates the effects of the soil deformation by shifting the natural frequency of the structure and increasing the global damping of the system. The amount of energy dissipated in the soil is demonstrated in the analysis of the modal damping
