Abstract

A preliminary measurement of R = F (K± → e ±ν̄e)/ F (K± → μ±ν̄μ) at the KLOE experiment is discussed. The result, R = (2.55 ± 0.05 ± 0.05)x 10-5, is based on 1.7 fb-1 of luminosity integrated on the ��-meson peak at the Frascati e +e- collider DAPdblNE, corresponding to ���8000 observed K�� ��� e�� �� ��e events. Perspectives on the methods planned to improve both the statistical and the systematic errors are briefly outlined.
