The KLOE experiment, running at the Frascati DA&Fgr;NE &fgr;‐factory since 1999, was designed to measure theR(&Vegr;′/&Vegr;) ratio to an accuracy of few 10−4. However, its physics program is wider thanCPviolation, covering both kaon and non‐kaon physics items. During the year 2000 data taking, ∼ 20 pb−1were collected and a total integrated luminosity of 200 pb−1is expected by the end of 2001. A wealth of measurements can be addressed with these data and a number of preliminary results have been already obtained using the year 2000 statistics, in particular on rareKSdecays. After a brief description of the detector, theKStagging technique is discussed. Preliminary measurements of BR(KS→ &pgr;+&pgr;−)/BR(KS→ &pgr;0&pgr;0) and BR(KS→ &pgr;ev) are then presented. Finally, the perspectives for future analyses are discussed. © 2002 American Institute of Physics
