Abstract
A search for time-integrated violation in (, ) decays is presented using of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the and decay chains. The difference in asymmetry between and , , is measured to be . This differs from the hypothesis of conservation by 3.5 standard deviations.

Charm and Anticharm—Not Quite the Same
Published 12 March 2012
Differences between the decay properties of charm-carrying mesons and those of their antiparticles may carry clues to the mystery of the missing antimatter in the Universe.
