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.

Inspire Record 81796 DOI 10.17182/hepdata.50301

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.

The cross sections are fitted by the formula CONST(C=A)*EXP(SLOPE*T)*(1+CO NST(C=B)/SQRT(S)).

Pi- p backward elastic scattering between 1.28 and 3.0 gev/c

Ott, R.J. ; Trischuk, J. ; Va'vra, J. ; et al.
Phys.Lett.B 42 (1972) 133-135, 1972.
Inspire Record 85045 DOI 10.17182/hepdata.76247

The differential cross-section for π - -p elastic scattering over the angular range 125° to 178° center of mass has been measured between 1.28 and 3.0 GeV/ c . Considerable structure is found and is discussed in terms of direct channel resonances.

A comparison of pi+ and pi- total cross-sections of light nuclei near the 3-3 resonance

Wilkin, Colin ; Cox, C.R. ; Domingo, J.J. ; et al.
Nucl.Phys.B 62 (1973) 61-85, 1973.
Inspire Record 83895 DOI 10.17182/hepdata.32488

The total cross sections of 4 He, 6 Li, 7 Li, 9 Be, 12 C and 32 S for positive and negative pions have been measured in the energy range 80 to 260 MeV in a transmission experiment. Coulomb corrections were applied using real parts of the forward nuclear amplitudes as determined from dispersion relations. At the lower energies there remain large residual differences between the π + and π − scattering on the isoscalar nuclei. These can be largely understood in terms of the Coulomb distortion.

Measurements of the proton proton total cross-sections by means of Coulomb scattering at the Cern intersecting storage rings

Amaldi, U. ; Biancastelli, R. ; Bosio, C. ; et al.
Phys.Lett.B 43 (1973) 231-236, 1973.
Inspire Record 74360 DOI 10.17182/hepdata.28156

Proton-proton elastic scattering has been measured at the CERN Intersecting Storage Rings in the four-momentum transfer range 0.001 ⩽… t …⩽ 0.015 GeV 2 at centre-of-mass energies of 23 and 31 GeV. The detection of Coulomb scattering and of its interference with nuclear scattering leads to the determination of the real part of the nuclear amplitude and of the total proton-proton cross section by the optical theorem.
