Query: Produzione di particelle strane in interazioni piombo-piombo e
  protone-piombo a 160 GeV/c per nucleone   This PhD thesis is about the production of strange particles in heavy-ion
collisions at high energy produced at the SPS CERN syncrotron. Results are from
experiment WA85 and WA97. They have been compared with VENUS and RQMD
simulations. An increase in strangeness production has been observed which
cannot be explained in terms of superposition of hadron-hadron collisions. It
is in favour of a QGP scenario, developed in the early stages of the collisions
