Dynamical Generation of Hyperon Resonances
In this talk we report on how, using a chiral unitary approach for the meson–baryon interactions , two octets of J π = 1/2 − baryon states and a singlet are generated dynamically, resulting in the case of strangeness S = −1 in two poles of the scattering matrix close to the nominal Λ(1405) resonance. We suggest experiments which could show evidence for the existence of these states.

متن کاملThe Hunt for the Dynamical Resonances in Chemical Reaction Dynamics: A Perspective on Historical Advances
The theoretical background and basic definition of the resonances in chemical reaction dynamics have been introduced in this article. The historical breakthrough in the experimental search for the reaction resonances has been reviewed in this report, with an emphasis on the crossed molecular beam apparatus. The research of the chemical reaction resonances has attracted many scientists’ attentio...
متن کاملComputer Software for Understanding Resonances and Resonance-Related Phenomena in Chemical Reactions
In numerical modelling of chemical reactions one calculates the scattering matrix for the required values of energy and angular momentum. Having done so, one still faces the non-trivial task of extracting detailed information about the reaction mechanism. We discuss the methods and numerical tools for such an analysis in terms of resonance poles and semiclassical trajectories. Our approach avoi...
متن کاملA dynamical model of the chemical bond: kinetic energy resonances between atomic electrons
While the theory of chemical bonding has advanced rapidly as more and more details of the quantum mechanical problem have been taken into account, surprisingly little effort has gone into the developement of intuitive models to interpret the results obtained by more sophisticated means. This article introduces an approach to chemical bonding, which should give a better connection between basic ...
