“…18 has the meaning of s ′ in Eq. (38).) As a result, the distortion of the α dependence of the signal due to the elementaryp∆ − → π − π − differential cross section growing towards α → 2 is less pronounced for β = 1.5 than for β = 1.…”

We study the manifestation of the ∆ ++ − ∆ − component of the deuteron wave function in the exclusive reactionpd → π − π − ∆ ++. Due to the large binding energy the internal motion in the ∆ − ∆ 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 ∆ − ∆ 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 ∆−∆ 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.
