Theoretical study of the Δ + + − Δ − configuration in the deuteron using an antiproton beam
Theoretical study of the Δ + + − Δ − configuration in the deuteron using an antiproton beam
We study the manifestation of the Δ++−Δ− component of the deuteron wave function in the exclusive reaction ¯pd→π−π−Δ++. Due to the large binding energy the internal motion in the Δ−Δ system is relativistic. We take this into account within the light-cone (LC) wave function formalism and, indeed, fou...

We study the manifestation of the Δ++−Δ− component of the deuteron wave function in the exclusive reaction ¯pd→π−π−Δ++. Due to the large binding energy the internal motion in the Δ−Δ system is relativistic. We take this into account within the light-cone (LC) wave function formalism and, indeed, found large differences between calculations based on the LC and nonrelativistic (NR) wave functions. We demonstrate that the consistent LC treatment of the Δ−Δ system plays the key role in the separation of the signal and background. Within the LC approach, the characteristic shape of the momentum distribution of the Δ−Δ bound system predicted by the meson-exchange model is well visible on the background of usual annihilations at beam momenta between 10 and 15 GeV/c. |
