Recent studies within the framework of chiral unitary theory produce the $\Lambda (1520)$ resonance, among several others, as a dynamically generated resonance from the interaction of the baryon decuplet and the meson octet. The $\Lambda…
We study the effects of $N^{*}(1440)$ resonance on the production of kaons, antikaons and antiprotons in heavy-ion collisions at subthreshold energies. Using free-space widths for the $\Delta(1232)$ and the $N^{*}(1440)$ resonance and…
