We suggest a unified description of baryon form factors iii terms of a two-component model with an intrinsic q³ structure and a meson qq cloud, parameterized in terms of vector mesons. We use this model to study the N - Δ form factors. The results are in excellent agreement with data. The N - Δ transition appears to be dominated by coupling to the ρ meson.

    The present status of the thermal model is reviewed and the recently discovered sharp peak in the K+/Ï€+ ratio is discussed in this framework. It is shown that the rapid change is related to a transition from a baryon-dominated hadronic gas to a meson-dominated one. Further experimental tests...

    The s-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons is studied in a unitarized coupled channel approach. We obtain & fair agreement for mass and width of several 3/2- resonance. In particular, the X(1820), the Λ(1520) and the Σ(1670) states are well...

    Using a chiral unitary approach for meson-baryon scattering in the strangeness zero sector, where the N*(1535) and Δ*(1700) resonances are dynamically generated, we study the reactions γp → π0ηp and γp → π0K0Σ+ at photon energies at which the final states...
