Charge and energy flow in π+p,K+p andpp interactions at 250 GeV/c

We present data on the flow of energy and charge in π+ p,K + p andpp interactions at 250 GeV/c. The energy and charge flow in the beam c.m. hemisphere is analysed in terms of the cluster-invariant Bialas-Ochs-Stodolsky variable λ=cot θ/E jet. The profile functionsdQ/dλ anddE/dλ indicate a widening inp T of jets between 32 and 250 GeV/c incident laboratory momentum, whereas the ratiodQ/dE is energy independent. The data are compared to μp deep-inelastic scattering resutls and to expectations from the single string LUND model, the Dual Parton Model and the two-string LUND model (FRITIOF).
