Pi- photoproduction from deuterium at laboratory energies 600 to 1250 mev

Scheffler, P.E. ; Walden, P.L. ;

The differential cross section for the reaction γ+n→π−+p was measured for laboratory photon energies between 600 and 1250 MeV, using a liquid deuterium target. The internal nucleon momentum distribution of the deuteron was used to calculate the major effect of using deuterium as a neutron target. The data show that the amplitude to excite the F15(1688) resonance is small, in agreement with a recent quark-model prediction.

High-energy elastic scattering of pi-plus-minus, k-minus, and anti-p on hydrogen at c.m. angles from 22 degrees to 180 degrees

Owen, D.P. ; Peterson, F.C. ; Orear, J. ; et al.
Phys.Rev. 181 (1969) 1794-1807, 1969.
Inspire Record 55381 DOI 10.17182/hepdata.5487

Elastic π±−p, K−−p, and p¯−p scattering cross sections have been measured using three different experimental arrangements covering the c.m. angular regions ∼20°-120°, ∼135°-169°, and ∼165°-180° at incident momenta from 6 to 17 GeV/c. In the region 130°-180°, only π±−p scattering was measured. In the angular region near 180°, the energy dependences and shapes of the π−p backward peaks were determined up to crossed-momentum transfers of u∼−2 (GeV/c)2. At all energies, the π+−p backward peak had a sharp dip at u=−0.13 (GeV/c)2, with no similar effect in the π−−p case. Nearly complete angular distributions of π−−p elastic scattering from 20° to 180° have been obtained at 6 and 10 GeV/c. These results at 6 and 10 GeV/c as well as at 8 GeV/c reveal a sharp dip in π−−p scattering at t=−3 (GeV/c)2. Several structures in the form of dips or shoulders were seen in the p¯−p angular distributions also, with less pronounced structure observed in K−−p scattering. At fixed momentum transfer, all cross sections when expressed as dσdt appear to be decreasing with increasing energy.

Photoproduction of $\pi^0$ from Hydrogen near the Second Pion-Nucleon Resonance

DeStaebler, H.C. ; Erickson, E.F. ; Hearn, Anthony C. ; et al.
Phys.Rev. 140 (1965) B336-B348, 1965.
Inspire Record 48749 DOI 10.17182/hepdata.26402

Angular distributions for π0 photoproduction from hydrogen at energies between 660 and 800 MeV and proton center-of-mass angles from 0° to 140° have been measured and analyzed. Some variation from a pure d32 state is seen in the resonance region. A possible high-momentum-transfer enhancement of the cross section is discussed.

Total cross-sections of protons, anti-protons, and pi and K mesons on hydrogen and deuterium in the momentum range 6-GeV/c to 22-GeV/c

Galbraith, W. ; Jenkins, E.W. ; Kycia, T.F. ; et al.

Inspire Record 48756 DOI 10.17182/hepdata.5477

The total cross sections σT of p, p¯, π±, and K± on hydrogen and deuterium have been measured between 6 and 22 GeVc at intervals of 2GeVc to an accuracy greater than previously reported. The method utilized was a conventional good-geometry transmission experiment with scintillation counters subtending various solid angles at targets of liquid H2 and D2. With the increase in statistical accuracy of the data, it was found that a previously adopted procedure of linearly extrapolating to zero solid angle the partial cross sections measured at finite solid angles was not a sufficiently accurate procedure from which to deduce σT. The particle-neutron cross sections are derived by applying the Glauber screening correction to the difference between the particle-deuteron and particle-proton cross sections. The cross sections σT(π+d) and σT(π−d) are equal at all measured momenta, which confirms the validity of charge symmetry up to 20GeVc. Results are presented showing the variation of cross sections with momentum; evidence is presented for a small but significant decrease in σT(pp) [and σT(pn)] in the momentum region above 12GeVc.
