Large angle differential cross-section for k+ p elastic scattering at 4.0 and 5.0 gev/c

Akerlof, C.W. ; Han, K.S. ; Meyer, D.I. ; et al.
Phys.Rev.Lett. 26 (1971) 1278-1279, 1971.
Inspire Record 68998 DOI 10.17182/hepdata.21514

We present data on the reaction K+p→K+p at large angles. Between the forward diffraction peak and the backward peak the cross section is independent of four-momentum transfer but varies with incident momentum.

Pi+- and pi0 production by polarized photons in the resonance region

Alspector, J. ; Fox, D. ; Luckey, David ; et al.
Phys.Rev.Lett. 28 (1972) 1403-1406, 1972.
Inspire Record 75484 DOI 10.17182/hepdata.21872

We have measured the cross sections at 90° c.m. for π± and π0 photoproduction with polarized photons. The photon energies ranged from 0.8 to 2.2 GeV. We compare the resonant "bumps" in the cross section with theoretical models. The measured asymmetry agrees with a quark-model calculation though the predicted cross sections are low.

Channel cross-sections of k- p reactions from 1.26 to 1.84 gev/c

de Bellefon, A. ; Berthon, A. ; Rangan, L.K. ; et al.
Nuovo Cim.A 7 (1972) 567-583, 1972.
Inspire Record 78277 DOI 10.17182/hepdata.37482

We present the results on total channel cross-sections obtained in the Saclay 180 l HBC exposed to a separated K− beam at Nimrod. The cross-sections for each channel are given at 13 incident K− momenta between 1.26 and 1.84 GeV/c.

K+ p cross-sections between 2.1 and 2.7 gev/c

Brunet, J.M. ; Narjoux, J.L. ; Danysz, J.A. ; et al.
Nucl.Phys.B 36 (1972) 45-57, 1972.
Inspire Record 75386 DOI 10.17182/hepdata.33006

Cross sections are presented for the K + p interacttions with 2, 3, 4 and 5 particles in the final state for incident momenta between 2.1 and 2.7 GeV/c. The results are compared with those from other experiments at nearby momenta.

K+ p elastic scattering between 2.11 and 2.72 gev/c

Danysz, J.A. ; Penney, B.K. ; Stewart, B.C. ; et al.
Nucl.Phys.B 42 (1972) 29-43, 1972.
Inspire Record 75131 DOI 10.17182/hepdata.32928

Final results are presented of the analysis of the elastic channel in an exposure of 40 000 pictures at each of the four incident K + momenta 2.11, 2.31, 2.5 and 2.72 GeV/ c taken in the 1.5 m British National Hydrogen Bubble Chamber at the 8 GeV/ c proton synchrotron at the Rutherford High Energy Laboratory. Differential cross sections are presented and the results are compared with other published data. A Legendre polynomial analysis requires partial waves up to G wave at all momenta. For the backward peak, visible at each momentum, the slope and the intercept are calculated. A comparison of the forward peak is made with extrapolations from Regge models fitted at higher momenta.

On helicity conservation in the reaction pi- p ---> a1 p at 4.45 gev/c

Beketov, G.V. ; Zombkovsky, S.M. ; Kaidalov, A.B. ; et al.
Nucl.Phys.B 59 (1973) 265-272, 1973.
Inspire Record 83967 DOI 10.17182/hepdata.32538

Helicity conservation in the reaction π − p → pA 1 at 4.45 GeV/ c has been studied using 50 cm and 55 cm liquid hydrogen bubble chambers. In the Jackson and the helicity frames the dependence of the ϱ matrix elements on the four-momentum transfer squared to the proton ( t ) for A 1 maximum decay has been calculated. The obtained data are in a good agreement with t -channel helicity conservation. The t -channel dependence of the ϱ matrix elements in the mentioned frames is in good agreement with that calculated using the Regge π-pole exchange model (it is suggested that the A 1 maximum nature is explained by a kinematical effect of the Deck type).

The Energy Dependence of Backward $\pi^+ p$ Elastic Scattering from 2 GeV/c to 6 GeV/c

Baker, W.F. ; Eartly, David P. ; Pretzl, K. ; et al.
Phys.Rev.Lett. 32 (1974) 251, 1974.
Inspire Record 80709 DOI 10.17182/hepdata.21310

The energy dependence of backward π+p elastic scattering has been measured for incident π momenta 2.0-6.0 GeV/c in steps of typically 100 MeV/c. Values are presented for both the differential cross section extrapolated to 180° and the slope of the backward peak as a function of momentum. In the s channel we see the effects of the established Δ++ resonances and evidence for the Δ(3230). Also, the data show the existence of a negative-parity Δ resonance with mass ∼2200 MeV/c2.

Proton Compton scattering at 0.55-to-4.5-gev energy and 0.12-to-1.0-(gev/c)-squared momentum transfer

Deutsch, M. ; Cleetus, K.J. ; Golub, L. ; et al.
Phys.Rev.D 8 (1973) 3828-3847, 1973.
Inspire Record 93270 DOI 10.17182/hepdata.22057

Results are presented on the elastic scattering of photons by protons. The incident photon energy ranged from 0.55 GeV to 4.5 GeV, and the four-momentum transfer t ranged from 0.12 to 1.0 (GeV/c)2. The data at large angles, 60°<θ*<115°, are characterized by a pronounced excitation of the D13(1518) resonance, a shoulder in the 1688-MeV mass region, and a precipitous drop thereafter in the cross section as a function of incident energy. The low-t data are characterized by a diffraction slope of 5 (GeV/c)−2. The data are inconsistent with the predictions of the vector-dominance model if the latter is restricted to ρ0, ω, and φ vector mesons.
