Elastic Scattering of $p^\pm$, $\pi^\pm$ and $K^\pm$ on Protons at High-energies and Small Momentum Transfer

Cool, R.L. ; Goulianos, Konstantin A. ; Segler, S.L. ; et al.
Phys.Rev.D 24 (1981) 2821, 1981.
Inspire Record 156145 DOI 10.17182/hepdata.24029

We report on a measurement of elastic differential cross sections for p±p, π±p, and K±p at 100 and 200 GeV/c in the range 0.03<|t|<0.10 (GeV/c)2. Our data display a simple exponential dependence which is consistent with other measurements in this t region or with extrapolations from higher t.

We report differential cross sections for h+p→X+p (h=π±,K±,p±) at 100 and 200 GeV/c in the region 0.025<|t|<0.095 (GeV/c)2 and MX2s<0.1.

Multiplicity of Secondary Particles in Inelastic Proton - Neon Interactions at 300-{GeV}/$c$

Azimov, S.A. ; Inogamov, Sh.V. ; Kosonovsky, E.A. ; et al.
Phys.Rev.D 23 (1981) 2512, 1981.
Inspire Record 10318 DOI 10.17182/hepdata.17871

The data on the total inelastic and partial cross sections in pNe interactions at 300 GeV are presented. It is found that the total cross section, σin(pNe)=356±13 mb, and multiplicity distributions of the number of negative and relativistic charged particles are in good agreement with predictions of a multiple-scattering model based on Glauber's approach. The multiplicity of negative particles obeys the Koba-Nielsen-Olesen (KNO) scaling, but it is observed that the KNO function depends on the atomic mass number of the target. From an analysis of the average multiplicities of secondary particles, it is shown that approximately 10 percent of the fast (p≳1.2 GeV) positive secondaries are protons, which are derived from the nucleons in the neon nucleus.

High $p_T$ Hadron Production in Photon - Photon Collisions

The TASSO collaboration Brandelik, R. ; Braunschweig, W. ; Gather, K. ; et al.
Phys.Lett.B 107 (1981) 290-296, 1981.
Inspire Record 167417 DOI 10.17182/hepdata.31027

We have studied the properties of hadron production in photon-photon scattering with tagged photons at the e + e − storage ring PETRA. A tail in the p T distribution of particles consistent with p T −4 has been observed. We show that this tail cannot be due to the hadronic part of the photon. Selected events with high p T particles are found to be consistent with a two-jet structure as expected from a point-like coupling of the photons to quarks. The lowest-order cross section predicted for γγ → q q , σ = 3 Σ e q 4 · σ γγ → μμ , is approached from above by the data at large transverse momenta.

Exclusive Proton - Anti-proton Production in Two Photon Collisions

Phys.Lett.B 108 (1982) 67-70, 1982.
Inspire Record 167679 DOI 10.17182/hepdata.31000

Production of proton-antiproton pairs by two-photon scattering has been observed at the electron-position storage ring PETRA. A total of eight proton-antiproton pairs have been identified using the time-of-flight technique. We have measured a total cross section of 4.5 ± 0.8 nb in the photon-photon c.m. energy range 2.0–2.6 GeV.

Proton - Deuteron Elastic Scattering From 20-{GeV} to 210-{GeV}

Warren, G. ; Gross, D. ; Olsen, S.L. ; et al.
Nucl.Phys.B 207 (1982) 365-373, 1982.
Inspire Record 11268 DOI 10.17182/hepdata.34079

Measurements of the differential cross section for proton-deuteron elastic scattering are reported for incident proton momenta ranging from 20 to 210 GeV and for invariant four-momentum transfers of 0.6 ≤ − t ≤ 3.0 GeV 2 . The results are in disagreement with a very simple Glauber double scattering model calculation.

$\pi^0$ Production by $e^+ e^-$ Annihilation at 14-{GeV} and 34-{GeV} Center-of-mass Energy

The process e + e − → π 0 + anything has been measured at c.m. energies of 14 and 34 GeV for π 0 energies between 0.5 and 4 GeV. The ratio of π 0 to π ± production for π momenta between 0.5 and 1.5 GeV/ c is measured to be 2 σ ( π 0 )/ [ σ ( π + ) + σ ( π − )] = 1.3 ± 0.4 (1.2 ± 0.4) at 14 (34) GeV. The scaled cross section ( s / μ )d σ /d x when compared with lower energy (4.9–7.4 GeV) π 0 data indicates a substantial scaling violation.

DECAY OF B MESONS INTO CHARGED AND NEUTRAL KAONS

The CLEO collaboration Brody, A. ; Chen, A. ; Goldberg, M. ; et al.
Phys.Rev.Lett. 48 (1982) 1070-1074, 1982.
Inspire Record 180612 DOI 10.17182/hepdata.27749

Data on inclusive kaon production in e+e− annihilations at energies in the vicinity of the ϒ(4S) resonance are presented. A clear excess of kaons is observed on the ϒ(4S) compared to the continuum. Under the assumption that the ϒ(4S) decays into BB¯, a total of 3.38±0.34±0.68 kaons per ϒ(4S) decay is found. In the context of the standard B-decay model this leads to a value for (b→c)(b→all) of 1.09±0.33±0.13.
