Abstract

A search for mixing in the neutral D meson system has been performed using semileptonic D0→K(*)-e+ν decays. Neutral D mesons from D*+→D0π+ decays are used; the flavor at production is tagged by the charge of the slow pion. The measurement is performed using 253 fb-1 of data recorded by the Belle detector. From the yield of right-sign and wrong-sign decays arising from nonmixed and mixed events, respectively, we estimate the upper limit of the time-integrated mixing rate to be rD<1.0×10-3 at 90% C.L. © 2005 The American Physical Society.
