Production of pi$^{0}$ at large transverse momentum in alpha.alpha and alpha.p collisions at the CERN Intersecting Storage Rings

Inclusive pi /sup 0/ production has been measured at the CERN Intersecting Storage Rings in alpha alpha and alpha p collisions near 90 degrees , for p/sub T/ between 2 and 5 GeV/c. The differential cross sections show a slower exponential fall-off with p/sub T/ than has been observed in pp collision...

Descripción
Sumario:Inclusive pi /sup 0/ production has been measured at the CERN Intersecting Storage Rings in alpha alpha and alpha p collisions near 90 degrees , for p/sub T/ between 2 and 5 GeV/c. The differential cross sections show a slower exponential fall-off with p/sub T/ than has been observed in pp collisions at the corresponding nucleon- nucleon centre-of-mass energies at large p/sub T/. The ratio of the pi /sup 0/ production cross sections for alpha alpha collisions to those for pp collisions is observed to be larger than 16. (8 refs).
