On the width of the $\Delta(1232)$ in $N\Delta$ and $\Delta\Delta$ states

Autor: Niskanen, Jouni A.

Due to the finite kinetic energy in the intermediate $N\Delta$ state the (internal) energy available for mesonic decay is decreased and consequently the effective $N\Delta$ width is suppressed in $NN$ scattering. The same can happen also in $\Delta$$

Binding vs. scattering length: $\eta$ in light nuclei

Autor: Niskanen, Jouni A., Machner, Hartmut

The possibility of etamesic nuclei remains an open problem in nuclear physics until now. Various calculations give contradictory predictions even for the lightest real nucleus $^3$He. In this paper we present the connection of the binding energy and

On the width of the Δ(1232) in NΔ and ΔΔ states

Autor: Niskanen Jouni A.

Publikováno v: EPJ Web of Conferences, Vol 199, p 02019 (2019)

Due to the finite kinetic energy in the intermediate NΔ state the (internal) energy available for mesonic decay is decreased and consequently the effective NΔ width is suppressed in NN scattering. The same can happen also in ΔΔ case. Also the NΔ
