High $p_T \pi^0$ Production From $\alpha \alpha$ and $\alpha p$ Collisions at the {CERN} {ISR}

The CERN-Oxford-Rockefeller collaboration Angelis, A.L.S. ; Basini, G. ; Besch, H.J. ; et al.

The invariant cross sections for π 0 meson production in alpha—alpha and alpha—proton collisions at the ISR were meas- ured up to transverse momenta of 7 GeV c and 8 GeV c , respectively. These measurements are compared with π 0 production in pp collisions at the same values of s / nucleon, and the variation of the nuclear A -dependence with p T is determined.

Production of $\pi^0$ at Large Transverse Momentum in $\alpha \alpha$ and $\alpha p$ Collisions at the {CERN} Intersecting Storage Rings

Inclusive π 0 production has been measured at the CERN Intersecting Storage Rings in αα and α p collisions near 90°, for p T between 2 and 5 GeV/c. The differential cross sections show a slower exponential fall-off with p T than has been observed in pp collisions at the corresponding nucleon-nucleon centre-of-mass energies at large p T . The ratio of the π 0 production cross sections for αα collisions to those for pp collisions is observed to be larger than 16.
