A study of neutral final states in k- p interactions in the range from 690 to 934 mev/c

Baxter, D.F. ; Buckingham, I.D. ; Corbett, I.F. ; et al.
Nucl.Phys.B 67 (1973) 125-156, 1973.
Inspire Record 94876 DOI 10.17182/hepdata.32387

The K − p reactions with final states Λπ 0 , Σ 0 π 0 , Λπ 0 π 0 , Λη and Σ 0 η have been studied at 14 momenta between 685 and 934 MeV/ c using optical spark chambers. The charged decay products of the Λ are detected by low mass spark chambers while γ-rays from π 0 and Σ 0 decays are detected in high mass chambers. Approximately 250 000 photographs were analysed from which partial and differential cross sections were determined. These results are presented with an energy dependent, single channel partial-wave analysis.

INVESTIGATION OF THE CHARGE EXCHANGE REACTION H-3 p ---> He-3 n AT 2.5-GeV/c TRITON MOMENTUM

Blinov, A.V. ; Chuvilo, I.V. ; Ergakov, V.A. ; et al.
J.Phys.G 8 (1982) 223, 1982.
Inspire Record 154213 DOI 10.17182/hepdata.40232

The differential cross sections d sigma /dt of the reactions 3H+p to 3He+n and 3H+p to 3H+p at a triton momentum of 2.5 GeV/c (equivalent to a proton kinetic energy Tp=318 MeV) have been measured. The ITEP 80 cm hydrogen bubble chamber was exposed to a 2.5 GeV/c separated triton beam. 2350 events of the reaction 3H(p,n)3He and 2574 events of the reaction 3H(p,p)3H were selected and analysed. Calculations performed in the framework of the multiple scattering theory taking the spin-isospin structure of the NN amplitude into account fit the data very well and show the high sensitivity of the charge-exchange cross section to the double spin-flip NN amplitudes.

INVESTIGATION ON THE REACTION t p ---> p d n AT 2.5-GeV/c TRITON MOMENTUM

Chuvilo, I.V. ; Ergakov, V.A. ; Grechko, V.E. ; et al.
Phys.Lett.B 91 (1980) 349-352, 1980.
Inspire Record 154345 DOI 10.17182/hepdata.40230

The reaction of tp → pdn in 4π geometry was investigated by exposition of an 80 cm liquid hydrogen bubble chamber to a t-nucleus beam of 2.5 GeV/ c momentum. The main characteristics of the reaction are described reasonably well by the pole approximation in the absolute normalization and without free parameters.

BACKWARD PRODUCTION OF THE B (1235) MESON IN 11.46-GEV/C PI+ P INTERACTIONS

Wong, M.K. ; Key, A.W. ; Schwarzschild, B.M. ; et al.
Phys.Rev.Lett. 46 (1981) 974, 1981.
Inspire Record 169864 DOI 10.17182/hepdata.20643

Evidence for the backward production of the B(1235) meson in the final state π+p→pfπ+ω at 11.46 GeV/c with σ(|u′|<1.5 GeV2)=1.28±0.26 μb is presented. When nucleon exchange is assumed to dominate, estimates for the SU(3) mixing parameter FD as well as the B coupling to the nucleon-antinucleon are given. Some indication of a narrow enhancement at M(π+ω)≃1.03 GeV/c2 is seen, but confirmation of this as a resonant state is not yet possible.

PARTIAL WAVE ANALYSIS OF THE K+ PI+ K- SYSTEM SEEN IN THE REACTION PI+ P ---> K+ PI+ K- P AT 11.46-GeV/c

Inspire Record 194990 DOI 10.17182/hepdata.23837

We present results of a hybrid-bubble-chamber experiment examining the reaction π+p→π+pK+K− at an incident momentum of 11.46 GeV/c. The total cross section for this channel is determined to be 87.2±6.4 μb. A partial-wave analysis of the K+π+K− system reveals no unambiguous evidence of resonant activity, although mass enhancements are noted in the JP=0− κ¯K+ (S wave), JP=2− fπ (S wave), and JP=2−, K¯*0(892)K+ (P wave). This is the first published report of the relative phases of the waves seen in this reaction. We comment on the influence this channel may have on A1 and A3 production.

Multiplicity of Charged Particles in 800-{GeV} $p p$ Interactions

The LEBC-MPS collaboration Ammar, R. ; Aziz, T. ; Banerjee, S. ; et al.
Phys.Lett.B 178 (1986) 124-128, 1986.
Inspire Record 231133 DOI 10.17182/hepdata.6558

Results are reported concerning the charged-particle multiplicity distribution obtained in an exposure of the high-resolution hydrogen bubble chamber LEBC to a beam of 800 GeV protons at the Fermilab MPS. This is the first time that such data have been available at this energy. The distribution of the number n ch of charged particles produced in inelastic interactions obeys KNO-scaling. The average multiplicity is 〈 n ch 〉 = 10.26±0.15. For n ch ⩾8 the data can be well fitted to a negative binomial. The difference between the overall experimental multiplicity distribution and that resulting from the latter fit is in agreement with the contribution expected from diffractive processes.

Inclusive Charm Cross-Sections in 800-GeV/c p p Interactions

The LEBC-MPS collaboration Ammar, R. ; Banerjee, S. ; Baland, J.F. ; et al.
Phys.Lett.B 183 (1987) 110, 1987.
Inspire Record 233423 DOI 10.17182/hepdata.42573

We report a measurement of the inclusive D/D̄ production cross section in 800 GeV/ c proton-proton interactions. The experiment used the high resolution bubble chamber LEBC exposed to an 800 GeV/ c proton beam at the Fermilab MPS. We obtain σ( D/ D ̄ )=59 −15 +22 μ b (statistical errors), having analysed 25% of the total data sample. Comparison with 400 GeV/ c pp dat a obtained with LEBC at CERN shows a D/D̄ cross section increase by a factor of 1.7 −0.5 +0.7 . This is in good agreement with fusion model calculations.
