摘要：
The measurement of strangeness is a valuable tool for understanding the reaction mechanism of nuclear collisions since all the strange particles need to be created during the reaction. Also, strangeness enhancement is one of the predicted signals of the QGP. In the present work we will discuss the behaviour of the strangeness production (i.e. K/pi ratio) with rapidity and baryo-chemical potential in Au+Au collisions at 62.4 A GeV. In this particular reaction, BRAHMS is able to identify particles over 3.5 rapidity units and thereby cover a wide range of (p) over bar /p ratios, including the fragmentation region. We will show spectra and ratios of identified particles as a function of p(T) and rapidity.
