Differential Cross-Section for pi- p --> eta0 n at 6.0-GeV/c

The Carleton-Michigan State-Ohio State-Toronto collaboration Shaevitz, M.H. ; Reay, N.W. ; Reibel, K. ; et al.
Phys.Rev.Lett. 36 (1976) 5, 1976.

We have measured the differential cross section for π−p→η0n at 6.0 GeV/c from 6730 very clean events in which the decay η→π+π−π0 was detected. The high statistics reveals a sizable forward turnover, implying a dominance of the helicity-flip amplitude. A precisely determined A2 trajectory, linear for |t|<1.0 (GeV/c)2, is found from combining our data with those at energies up to 101 GeV.

Inclusive Cross-Sections for 180-Degree Production of High-Energy Protons, Deuterons, and Tritons in p-Nucleus Collisions at 600-MeV and 800-MeV

Frankel, S. ; Frati, W. ; Van Dyck, O. ; et al.

The inclusive cross sections, measured up to large values of effective mass (≡q22ν), are well fitted by dσd3p=Bxexp(−αxp22mx). Values of Bx and αx are given for Be, C, Cu, and Ta at the incident proton energy of 600 MeV and for Ag, Ta, and Pt at 800 MeV. Extremely large dp and tp ratios and large A and q2 dependences of the relative cross sections are observed.

New Data on the Reaction K- p --> Sigma+- pi+- from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analysis for These Reactions, Between 2070-MeV and 2436-MeV CMS Energy

Nuovo Cim.A 37 (1977) 175, 1977.
Inspire Record 100939 DOI 10.17182/hepdata.37615

We present the results of a formation experiment for the reactions K±p→Σ±π± in the c.m.s. energy between 2200 and 2436 MeV with a total statistics of 10 ev/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in theD15,G19 andH09 states and confirms the existence of anF05 state.

Omega Production in the Reaction pi- p --> pi+ pi- pi0 n at 8-GeV/c and 12-GeV/c

Dowell, J.D. ; Garvey, J. ; Jobes, M. ; et al.
Nucl.Phys.B 108 (1976) 30-44, 1976.
Inspire Record 100856 DOI 10.17182/hepdata.35781

The reaction π − p → ω n has been studied at 8 and 12 GeV / c incident momenta with the CERN Omega spectrometer using a neutron time of flight trigger. The differential cross sections and the ω-decay density matrix elements are presented as functions of the momentum transfer squared − t in the range of 0.02 to 0.80 GeV 2 . The data are used to evaluate the intercept and slope of both the natural and unnatural parity exchange trajectories. Regge exchange amplitude factorisation tests involving the reaction π N → ω N are investigated.

Inclusive Delta++ Production in K+ p Interactions at 8.2-GeV/c and 16-GeV/c

Chliapnikov, P.V. ; Gumenyuk, S.A. ; Rubin, A.M. ; et al.
Nucl.Phys.B 105 (1976) 510-526, 1976.
Inspire Record 101055 DOI 10.17182/hepdata.35924

The reaction K + p→ Δ ++ (1236)+ anything is studied at beam momenta 8.2 and 16 GeV/ c and compared with other Δ ++ producing reactions. We find that the low-mass Δ ++ π − enhancement affects the shapes of Δ ++ inclusive distributions. The triple-Regge formula is found to be consistent with the data. Dual properties of this formula are successfully tested.

Inclusive Pion and eta Production in K- p Interactions at 14.3-GeV/c

Borg, A.C. ; Bardadin-Otwinowska, M. ; Barloutaud, R. ; et al.
Nucl.Phys.B 106 (1976) 430-450, 1976.
Inspire Record 100813 DOI 10.17182/hepdata.8392

The inclusive cross sections for π − , π 0 , π + and η production in K − p interactions at 14.3 GeV/ c are calculated. The invariant cross section distributions are presented and compared in the whole phase space for π + and π 0 , and in the backward c.m. region for π − . In the fragmentation regions, the charged pion production is analysed in terms of the triple-Regge model.

K0 and Lambda Production at the CERN ISR

Busser, F.W. ; Camilleri, L. ; Di Lella, L. ; et al.
Phys.Lett.B 61 (1976) 309-312, 1976.
Inspire Record 101076 DOI 10.17182/hepdata.5534

Transverse momentum distributions of λ o , λ o , and K o , produced in pp collisions at x = 0, have obtained at the CERN ISR. The K o yield is in agreement with published K + , K − results, obtained at this centre-of-mass energy (√ s ≈44 GeV). The results on λ o and λ o production obtained in this experiment are compared with results obtained at lower centre-of-mass energies.

Inclusive Photoproduction of Charged Particles in the Forward Hemisphere

Boyarski, A. ; Coward, D.H. ; Ecklund, Stanley D. ; et al.
Phys.Rev.D 14 (1976) 1733, 1976.
Inspire Record 101256 DOI 10.17182/hepdata.4891

We report measurements of the invariant cross section in the forward hemisphere for inclusive photoproduction of π±, K±, p, and p¯ from hydrogen and deuterium with an incident photon energy of 18 GeV. A small amount of data was also taken at incident energies of 9 and 13 GeV. The measurements were made using the SLAC 20-GeV/c spectrometer, and a bremsstrahlung-subtraction technique was used to obtain the cross sections at the specified incident energy. The data are compared with those from lower-energy experiments and interpreted within the context of the Mueller-Regge model and the constituent-interchange model.
