Description
Summary: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 | t| < 4 (GeV/ c) 2. The effective trajectory obtained from fits to the M 2/ s distribution in different t bins is α R ( t) = −(0.38 ± 0.11) + (1.15 ± 0.07) t, which holds up to a | 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.
