Effects of N${}^{\ast }$(1440) resonance on subthreshold kaon, antikaon and antiproton production

Bao-An Li, Che Ming Ko, Guoqiang Li

We study the effects of $N^{\ast }(1440)$ resonance on the production of kaons, antikaons and antiprotons in heavy-ion collisions at subthreshold energies. Using free-space widths for…
