A triple-Regge analysis of the inclusive reaction pp→Λ+X++ at 19 GeV/c

The inclusive reaction pp→Λ+X++ at 19 GeV/c beam momentum has been analyzed in terms of the triple-Regge formalism. A good description of the structure function is achieved for events with mod(t)<4 (GeV/c)2. The effective trajectory obtained from fits to the M2/s distribution in different t bins is αsub(R)(t) = -(0.38+-0.11)+(1.15+-0.07)t, which holds up to a mod(t) value of 4 (GeV/c)2. This is consistent with the K trajectory rather than the K* trajectory which has been reported from other experiments. (Auth.)
