Inclusive $\rho^0$ and $f^0$ Production in 100-GeV/c $\bar{p}p$ Interactions

Raja, R. ; Murphy, C.T. ; Voyvodic, L. ; et al.
Phys.Rev.D 16 (1977) 2733, 1977.
Inspire Record 119859 DOI 10.17182/hepdata.24478

Inclusive and semi-inclusive $ρ^0$ production in 100-GeV/c $\bar{p}p$ interactions has been studied as a function of c.m. rapidity and transverse momentum. Cross sections are compared with those for $\bar{p}p$ interactions at other energies, as well as pp and π±p interactions, over the range ∼2 < $p_{lab} < 200$ GeV/c. A measurement of the $f^0$ production cross section has been made. Calculations of the contribution from $\rho^0$ decay to prompt lepton production are presented.

Properties of Inclusive $\pi^{\pm}$ Production in 100 GeV/c Antiproton-Proton Interactions

Whitmore, J. ; Oh, B.Y. ; Pratap, M. ; et al.
Phys.Rev.Lett. 38 (1977) 996, 1977.
Inspire Record 118838 DOI 10.17182/hepdata.20985

Inclusive spectra are presented for π± production in 100-GeV/cp¯p interactions. The rapidity distribution for the difference (p¯p−pp) approximately scales as the difference in total cross sections in the fragmentation region between 12 and 100 GeV/c and exhibits an approximate s−12dependence in the central region.

Tests of Factorization from Single and Double Pion Production in 100 GeV/c $\bar{p}p$ and pp Collisions.

Rushbrooke, John G. ; Ward, D.R. ; Ansorge, R.E. ; et al.
Phys.Rev.Lett. 39 (1977) 117-120, 1977.
Inspire Record 123282 DOI 10.17182/hepdata.20980

Single- and double-pion inclusive spectra are presented for 100-GeV/c p¯p interactions and compared with related pp data. Double-fragmentation distributions are shown to be understood within a Mueller-Regge framework as a product of single-fragmentation distributions. Consideration of pp and p¯p−pp distributions shows factorization to hold in Pomeron and in Reggeon exchanges independently.

Neutral Particle Production in 100 GeV/c $\bar{p}p$ Interactions

Raja, R. ; Moore, Craig D. ; Voyvodic, L. ; et al.
Phys.Rev.D 15 (1977) 627, 1977.
Inspire Record 110399 DOI 10.17182/hepdata.24539

We have investigated the inclusive production of γ, KS0, Λ0, and Λ¯0 in 100-GeV/c p¯p interactions in the 30-in. hydrogen bubble chamber at Fermilab. We present various inclusive distributions and compare them with corresponding distributions in 100-GeV/c pp interactions and lower-energy p¯p interactions. We find some evidence for Σ(1385) production but none for K*(890) production. We find evidence for a nonzero Λ0 polarization of -0.45 ± 0.21.

Comparison of Neutral Particle Production in 100 GeV/c $\bar{p}p$ and pp Interactions.

Ward, D.R. ; Ansorge, R.E. ; Bust, C.P. ; et al.
Phys.Lett.B 62 (1976) 237-240, 1976.
Inspire Record 112616 DOI 10.17182/hepdata.5528

We derive cross-sections for the inclusive productiion in p̄p interactions at 100 GeV /c of π 0 , K S 0 and Λ 0 Λ 0 of 91.5±5.7 mb, 5.2±0.4 mb and 4.8±0.4 mb respectively, which are all higher than pp cross-sections at energy. We find indications that these differences can be attributed to “annihilation” processes.

Production of $\gamma, \Lambda^0, K^0_s$ and $\bar \Lambda^0$ in pp Collisions at 102 GeV/c.

Chapman, J.W. ; Cooper, John W. ; Green, N. ; et al.
Phys.Lett.B 47 (1973) 465-468, 1973.
Inspire Record 81963 DOI 10.17182/hepdata.28029

We have measured cross section for γ , K S °, Λ and Λ production at 102 GeV/ c and find: σ ( γ ) = 170 ± 16 mb ., σ ( K S °) = 4.6 ± 0.5 mb ., σ ( Λ ) = 3.2 ± 0.4 mb ., and σ( Λ ) = 0.23 ± 0.10 mb. Both 〈 n π °〉 and 〈 n Ks °〉 appear to rise linearly with n - while the ratio 〈 n Ks °〉/〈 n π °〉 is approximately independent of n - . The integrated invariant cross section as a function of x as well as d σ /d y and d σ /d p T 2 are presented and compared with other data.
