THIS HADRON PAIR CROSS SECTION PROVIDES ONLY AN UPPER LIMIT TO THE PION FORM FACTOR ABOVE 1.5 GEV SINCE KAON PRODUCTION IS NOT DISTINGUISHED.


Measurement of inclusive photoproduction at 3.2 gev and comparison with electroproduction

Burfeindt, H. ; Buschhorn, G. ; Genzel, H. ; et al.
Phys.Lett.B 43 (1973) 345-348, 1973.
Inspire Record 84913 DOI 10.17182/hepdata.45255

Inclusive photoproduction cross sections for pions, kaons and protons have been measured in the photon fragmentation region and are compared with recent electroproduction data at q 2 = 1.16 (GeV/ c ) 2 . If the cross sections are normalized to the total hadronic cross sections at q 2 = 0 and q 2 = 1.16 (GeV/ c ) 2 , respectively, we observe that more pions, about an equal number of protons, but fewer kaons are found in the photoproduction case for x ≥ 0.3.

Observation of increasing charged multiplicity as a function of transverse momentum in 28.5-gev/c p p interactions

Ramanauskas, A. ; Anderson, E.W. ; Fisher, G.P. ; et al.
Phys.Rev.Lett. 31 (1973) 1371-1374, 1973.
Inspire Record 83758 DOI 10.17182/hepdata.47029

We have measured the mean charged multiplicity n¯CH as a function of transverse momentum p⊥ of the forward proton in the reaction p+p→p+MM for five intervals of missing mass (MM) using our Multiparticle Argo Spectrometer System. We observe an increase of n¯CH for p⊥>1 GeV/c.

Vector-meson electroproduction at high q-squared

Ahrens, L. ; Berkelman, Karl ; Brown, G.S. ; et al.
Phys.Rev.Lett. 31 (1973) 131-133, 1973.
Inspire Record 84487 DOI 10.17182/hepdata.47133

We have measured ρ0, ω (combined) and ϕ electroproduction over a range of virtual-photon four-momentum Q2 from 0.4 to 2.2 GeV2 and for photon energies ν from 2.7 to 8.6 GeV. We find that the slope of the t (momentum transfer) dependence of the ρ0 and ω forward peak decreases with increasing Q2 to less than half of the photoproduction slope.

The cross section for virtual photon are derived from E- P cross section bydividing on the virtual-photon flux factor.


Measurement of the polarization parameter of the reactions pi- p ---> pi0 n and eta n at 5 and 8 gev/c

Bonamy, P. ; Borgeaud, P. ; Crozon, M. ; et al.
Nucl.Phys.B 52 (1973) 392-402, 1973.
Inspire Record 84261 DOI 10.17182/hepdata.50104

Measurements of the polarization parameter of the reactions π − p → π 0 n and π − p → η n at 4.90 and 7.85 GeV/ c and for a squared four-momentum transfer − t ranging from 0.1 to 2.0 (GeV/ c ) 2 have been achieved by using a butanol polarized proton target and detecting only the two γ's from the neutral meson decay. The background due to events involving bound protons has been separately measured and subtracted out. A large positive polarization has been found for the reaction π − p → π 0 n. It is consistent with other pion-nucleon scattering data connected by isospin conservation. The polarization for the reaction π − p → η n is not significantly different from zero within the large experimental errors.

We present measurements of the invariant cross section for the inclusive reaction p+p→p+X in the region 0.14<|t|<0.38 GeV2, 100<s<750 GeV2, and 0.80<x<0.93.
