Helicity Amplitudes of the Λ(1670) and two Λ(1405) as dynamically generated resonances
We determine the helicity amplitudes A1/2 and radiative decay widths in the transition Λ(1670) → γY (Y = Λ or Σ). The Λ(1670) is treated as a dynamically generated resonance in mesonbaryon chiral dynamics. We obtain the radiative decay widths of the Λ(1670) to γΛ as 3 ± 2 keV and to γΣ as 120 ± 50 keV. Also, the Q dependence of the helicity amplitudes A1/2 is calculated. We find that the KΞ com...
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 کاملHelicity Amplitudes and Electromagnetic Decays of Strange Baryon Resonances
We present results for the helicity amplitudes of the lowest-lying hyperon resonances Y , computed within the framework of the Bonn constituent-quark model, which is based on the Bethe-Salpeter approach 1,2,3. The seven parameters entering the model are fitted against the best known baryon masses 4. Accordingly, the results for the helicity amplitudes are genuine predictions. Some hyperon reson...
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...
متن کاملDynamically Generated Hidden-charm Baryon Resonances
Received Day Month Year Revised Day Month Year Identifying a zero-range exchange of vector mesons as the driving force for the s-wave scattering of pseudo-scalar mesons off the baryon ground states, a rich spectrum of hadronic nuclei is formed. We argue that chiral symmetry and large-Nc considerations determine that part of the interaction which generates the spectrum. We suggest the existence ...
