$ΛΛ$ interaction and hypernuclei

C. Albertus, J. E. Amaro, J. Nieves

Data on $ΛΛ$ hypernuclei provide a unique method to learn details about the strangeness S =- 2 sector of the baryon-baryon interaction. From the free space Bonn-Jülich potentials,…

Pion Production in Neutrino-Nucleon Reactions

E. Hernandez, J. Nieves, M. Valverde

We construct a model for the weak pion production off the nucleon, which in addition to the weak excitation of the $Δ (1232)$ resonance and its subsequent decay into $N π$ , it includ…

Combined nonrelativistic constituent quark model and heavy quark effective theory study of semileptonic decays of Λ_b and Ξ_b baryons

C. Albertus, E. Hernandez, J. Nieves

We present the results of a nonrelativistic constituent quark model study of the semileptonic decays $Λ_{b}^{0} \to Λ_{c}^{+} l^{-} ν ˉ_{l}$ and $Ξ_{b}^{0} \to Ξ_{c}^{+} l^{-} ν ˉ_{l}$ . We work…

Quark-mass dependence of baryon resonances

M. F. M. Lutz, C. García-Recio, E. E. Kolomeitsev +1

We study the quark-mass dependence of J^P = \frac12^- s-wave and J^P = \frac32^- d-wave baryon resonances. Parameter-free results are obtained in terms of the leading order chiral…
