Dynamically generated resonances from vector meson-vector meson interaction based on a hidden-gauge unitary approach
We present a recent study of vector meson-vector meson interaction using a unitary approach based on the hidden-gauge Lagrangians. We find that 11 states get dynamically generated, corresponding to poles of the scattering matrices on the second Riemann sheet. Five of them are associated to the f0(1370), f0(1710), f2(1270), f ′ 2(1525), and K ∗ 2 (1430), by comparing the mass, width, and decay p...
متن کاملDynamically generated resonances from the vector octet-baryon octet interaction
We study the interaction of vector mesons with the octet of stable baryons in the framework of the local hidden gauge formalism using a coupled channels unitary approach. We examine the scattering amplitudes and their poles, which can be associated to known JP = 1/2−, 3/2− baryon resonances, in some cases, or give predictions in other ones. The formalism employed produces doublets of degenerate...
متن کاملDynamically Generated Resonances in the Chiral Unitary Approach to Meson Baryon Interaction
In this talk we report on the use of a chiral unitary approach for the interaction of the octets of meson and baryon and the octet of mesons with the decuplet of baryons. Two octets of Jπ = 1/2− baryon states and a singlet are generated dynamically in the first case, resulting in the case of strangeness S = −1 in two poles of the scattering matrix close to the nominal Λ(1405) resonance. In the ...
متن کاملDynamically generated resonances
In this talk I report on recent work related to the dynamical generation of baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a third type from two meson-one baryon systems. We can establish a correspondence with known baryonic resonances, reinforcing conclusions previously drawn and bringing new light on the nature of some baryonic resonances...
متن کاملLow lying axial - vector mesons as dynamically generated resonances
We make a theoretical study of the s-wave interaction of the nonet of vector mesons with the octet of pseudoscalar mesons starting from the Weinberg-Tomozawa Lagrangian and implementing unitarity in coupled channels. By looking for poles in the unphysical Riemann sheets of the unitarized scattering amplitudes, we get two octets and one singlet of axial-vector dynamically generated resonances. T...
