Using the $K^{+} p \to π^{+} K^{+} n$ reaction to determine the $Θ^{+}$ quantum numbers

E. Oset, T. Hyodo, A. Hosaka

We study the $K^{+} p \to π^{+} K^{+} n$ reaction with some kinematics suited to the production of the $Θ^{+}$ resonance recently observed and show that the measurement of cross sections and p…

Nuclear medium effects on the sigma mass and width

M. J. Vicente Vacas, E. Oset

The meson meson interaction in the scalar isoscalar channel at finite baryonic density is studied in the framework of a chiral unitary approach which generates the f0 and sigma res…
