K+/-e2 search and Lepton Flavor Violation at KLOE

This paper is devoted to the first analyses based on the complete data sample collected by the KLOE detector at DAPHNE, the Frascati phi-factory. The result for the BR(K_S -> gammagamma) and the search for the decay K_S->e+e- are presented. Particular emphasis is put on the measurement of the ratio of Ke2 and Kmu2 BRs.
