The s Dependence of Proton Fragmentation by Hadrons. 2. Incident Lab Momenta 30-GeV/c - 250-GeV/c

Weisberg, H. ; Beier, E. ; Brody, H. ; et al.

Measurements of inclusive scattering in the target-fragmentation region are extended to higher incident energy. The combined data set shows departures from an approach to the asymptotic scaling limit as A+Bs−12 that are significant even at the highest energies. When these departures are taken into account, the data approach a limit that is consistent with equal cross sections induced by particles and antiparticles and with Pomeron factorization. The corrections to A+Bs−12 are so large that detailed tests of Mueller-Regge relationships are not conclusive.

Forward Produced Protons and Anti-protons in Deep Inelastic Muon Proton Scattering

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.

Phys.Lett.B 103 (1981) 388, 1981.

Inspire Record 166178 DOI 10.17182/hepdata.31185

A significant rate of forward proton and antiproton production has been observed in 120 and 280 GeV muon-proton scattering. The z and p T 2 distributions are presented. The dependence of the normalized production cross section on the muon variables x and Q 2 is studied.

Inclusive Strange Particle Production in pi+ p Interactions at 16-GeV/c

The Aachen-Bonn-CERN-Cracow collaboration Bosetti, P. ; Böckmann, Klaus ; Cocconi, Vanna T. ; et al.

Nucl.Phys.B 94 (1975) 21-38, 1975.

Inspire Record 99424 DOI 10.17182/hepdata.32002

The production of K S 0 , Λ and Λ is measured in π + p reactions at 16 GeV/ c . The total strange particle cross section is found to be 4.0 ± 0.3 mb, about 20% of the inelastic cross section. Cross sections for single strange particles and for strange particle pairs are determined, both inclusively and as functions of the charged multiplicity. Relative production rates for different strange particle combinations are compared with the prediction of the isospin statistical model. Inclusive spectra for single particles are studied and it is found the K S 0 are produced mostly in the forward hemisphere, most probably by fragmentation of the incident pion into K K π . The Λ are mostly backwards, probably deriving from fragmentation of the proton into ΛK pairs. The Λ tend to be produced forwards, but evidence is found for central Λ Λ production. Distributions in rapidity of the Λ particles from π + p interactions are compared in terms of the factorisation hypothesis. Results are given on the Λ transversal polarisation.

Inclusive anti-K* (890) Production in pi- p Interactions at 16-GeV/c

Inclusive K ∗0 production is studied in π − p interactions at 16 GeV/ c with x ϝ > 0.2. The K ∗0 is found to be pre-dominantly centrally produced with cross section σ( K ∗0 ) = (72 ± 12) μb for x ϝ > 0.2 and compares closely to data on K ∗0 production in π + p interactions at the same energy.
