Abstract

A study is made of the ωπ 0 system produced near threshold in the reaction γ p→ π + π − π 0 π 0 p. A spin-parity analysis shows that the ωπ 0 enhancement is consistent with predominant 1 + B(1235) production, with ∼20% J P = 1 − background.

Abstract

Inclusive photoproduction of ϕ,K *0(890), $$\bar K*^0 $$ andK *0(1420), $$\bar K*^0 $$ has been studied in γp collisions with photons of energy 20 to 70 GeV and in the range 0.1≦x F ≦0.95 [0.4≦x F ≦0.8 for the $$\mathop K\limits^{( - )} *$$ (1420)],x F being the Feynman variable of the vector/tensor meson. The cross-sections for these processes, averaged over the photon energy range and integrated overx F are given. The inclusive ϕ production in the forward direction can be described quantitatively by a triple-Regge model calculation. The remaining ϕ production and the totalK *0(890) and $$\bar K*^0 $$ production are consistent with a quark fusion picture.

Abstract

Inclusive photoproduction of δ±(980) and B±0(1235) at high xF is reported. Production of B0 is largely due to double diffractive dissociation. The charged states are produced as leading particles, their production being described by the quark recombination picture. The relatively strong production of the δ(980) by this process is evidence that it is a qq state rather than a qqqq state.
