Abstract
The NA44 Collaboration has measured yields and differential distributions o f K+, K-, pi(+), pi(-) in transverse kinetic energy and rapidity, around th e center-of-mass rapidity in 158 A GeV/c Pb + Pb collisions at the CERN SPS . A considerable enhancement of K+ production per pi is observed, as compar ed to p + p collisions at this energy. To illustrate the importance of seco ndary hadron rescattering as an enhancement mechanism, we compare strangene ss production at the SPS and AGS with predictions of the transport model RQ MD.
