Identifying the quark content of the isoscalar scalar mesons f_0(980), f_0(1370), and f_0(1500) from weak and electromagnetic processes

Frieder Kleefeld, Eef van Beveren, George Rupp +1

The assignments of the isoscalar scalar mesons f0(980), f0(1370), and f0(1500) in terms of their qqbar substructure is still a matter of heated dispute. Here we employ the weak and…

F. Kleefeld

The present status of the theoretical description of Initial (ISI) and Final State Interactions (FSI) in nucleon induced exclusive meson production processes close to threshold is…

The pionic width of the $ω (782)$ meson within a well-defined, unitary quantum field theory of (anti-)particles and (anti-)holes

Frieder Kleefeld, Eef van Beveren, George Rupp

We investigate the indirect generation of the partial width of the $ω (782)$ meson with respect to the reaction $ω (782) \to ρ (770) π \to π^{+} π^{-} π^{0}$ within the context of a ``Unitary E…
