Kaon Phase Space Density in Heavy Ion Collisions
Abstract
The first measurement of kaon phase space densities are presented as a function of transverse mass, center of mass energy and the number of participants. The kaon phase space density increases with the number of participants from e+e- to Pb+Pb collisions. However the ratio of the kaon and pion phase space densities at low transverse momentum is independent of the number of participants for sqrt{s}=17GeV/nucleon This paper is dedicated to Francis Riccardelli, engineer for the Port Authority, who died on September 11th 2001 while evacuating others.

4 pages, 2 eps figures, proceedings of Strange Quarks in Matter, Frankfurt 2001, submitted to J. Phys. G In response to referees comments I derived an expresion for the ratio of kaon and pion phase space densites and made several clarifications in the text
