    abstract = "A search for the decay K-S –> e(+)e(-) was performed within the
framework of the CPLEAR experiment. Full event reconstruction together
with e/pi separation allowed powerful background rejection and high
signal acceptance. The analysis of the complete set of data yields the
result: BR(K-S –> e(+)e(-)) < 1.4 x 10(-7) (90% CL), an improvement on
the current experimental limit by a factor of 20. (C) 1997 Published by
