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.

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.

Study of the a2- from the reaction pi- p ---> k(s)0 k- p at 4.5 gev/c

Phys.Lett.B 35 (1971) 185-188, 1971.
Inspire Record 69246 DOI 10.17182/hepdata.28512

We present a study of A − 2 →K O S K − from the reaction π − p→K O S K − p at 4.5 GeV/ c in the 82-in. hydrogen bubble chamber. From a sample of 542 events from this final state, the mass (and its possible fine structure), width, production distribution and decay correlations of A − 2 are examined.

Anti-proton-neutron elastic scattering at 3.5 gev/c

Reynolds, B.G. ; Weaver, K.E. ; Bishop, J.M. ; et al.
Phys.Rev.D 2 (1970) 1767-1776, 1970.
Inspire Record 61323 DOI 10.17182/hepdata.4323

We have measured the p¯n differential elastic cross section for −t≥0.15 (GeV/c)2. We compare our data with existing data from p¯p and np elastic scattering experiments in this energy region. Our data show a dip in the cross section at −t≃0.45 (GeV/c)2 and a secondary maximum at −t≃0.7 (GeV/c)2. We see no evidence for backward peaking in p¯n elastic scattering at this energy. Evidence is presented for I=1, t-channel exchange in N¯N scattering.

Production of the g(1640) Meson in pi p Interactions at 6 GeV/c

Phys.Lett.B 28 (1968) 136-139, 1968.
Inspire Record 54727 DOI 10.17182/hepdata.29107

We present the results of a spin determination of the g 1 − (1640) meson from an analysis of its dipion decay mode (π − π 0 ), and find that spin three (or maybe greater) is favored [1,2]. We also report on the observation of an isospin one KK̄ enhancement at 1640 MeV which is consistent with a new decay mode of the g meson. A relative branching ratio of (K K ̄ /ππ) = 8 ± 3 8 % is obtain from our analysis.

K+ P ELASTIC SCATTERING AT 3.5-GeV/c AND 5.0-GeV/c

De Baere, W. ; Debaisieux, J. ; Dufour, J.P. ; et al.
Nuovo Cim.A 45 (1966) 885, 1966.
Inspire Record 50048 DOI 10.17182/hepdata.37572

The elastic scattering of K+ mesons on protons is studied at 3.5 and 5 GeV/c. The total elastic cross-sections are found to be (4.36±0.36) mb and (3.82±0.41) mb respectively. The differential elastic cross-sections, which exhibit characteristic diffraction peaks, are fitted by dσ/dt=(dσ/dt)0eαt, giving α=(3.85±0.12) and (4.70±0.21) (GeV/c)−2 for the two momenta respectively, with |t|⪝0.65 (GeV/c)2. The results are compared to those at neighbouring energies, giving some support to the presence of a real part of the forward scattering amplitude. The diffraction peak shows definite shrinking with increasing momenta. The data are examined in the light of models for high-energy scattering.
