New results from NA49

Abstract

Recent results of the NA49 experiment are presented. These cover first results on pion and kaon production, HBT, and charge fluctuations from Pb+Pb reactions at 40A GeV and their comparison to 158A GeV beam energy. Furthermore a study on baryon number transfer in p+p, centrality selected p+Pb and Pb+Pb collisions at 158A GeV and new results on the system size dependence of kaon yields, including C+C and Si+Si data, are presented. Additionally, a first result on $\Lambda$ $\Lambda$ correlations is shown
