MEASUREMENTS OF D (SIGMA) DE (T) IN COLLISIONS OF LIGHT NUCLEI AT S(NN)**(1/2) = 31.5-GEV

The AXIAL FIELD SPECTROMETER collaboration Akesson, T. ; Albrow, M.G. ; Almehed, S. ; et al.
Phys.Lett.B 231 (1989) 359-364, 1989.

Calorimeter measurements of dσ de t for pp, dd, pα , and αα collisions at S nn =31.5 GeV are presented for the pseudorapidity interval | η cm | ⩽ 0.7, extending over eight decades to E t ⩾ 30 GeV. The data are compared with models that predict nuclear cross sections directly from pp data, under the assumption of independent nucleon scatters.

Composition of Particles Emitted at Large $p_T$ and Medium Angles in $p p$, $d d$, and $\alpha \alpha$ Collisions at the {CERN} Intersecting Storage Rings

The Ames-Bologna-CERN-Dortmund-Heidelberg-LBL-Lund-Warsaw collaboration Breakstone, A. ; Claesson, G. ; Crawley, H.B. ; et al.
Z.Phys.C 30 (1986) 507, 1986.

The relative yields of kaons and protons compared with the yield of pions at highpT and polar angles θ away from 90° (in the range from 10° to 45°) are presented forpp, dd, and αα interactions at a centre-of-mass energy\(\sqrt {s_{NN} }= 31\) GeV per nucleon-nucleon collision. The measured particle ratios depend on the atomic mass numberA of the beam particles and on θ. TheA dependence of the ratios becomes stronger for largerpT and is more pronounced at smaller polar angles.
