Abstract

The inclusive production of Σ+ in K-p interactions at 4.2 GeV/c has been studied. Both the target fragmentation of the proton into Σ+ and the beam fragmentation of the kaon into Σ+ have been analysed with a triple-Regge model. In the pΣ-+channel an effective exchange trajectory has been obtained which lies between the K and K(890) trajectories. For the K-Σ-+channel a trajectory is found which may be interpreted as a Δ trajectory lowered by one-half.
