Zusammenfassung:	(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) The decay B ^sup 0^ [arrow right] DK ^sup 0^ and the charge conjugate mode are studied using 1.0 fb^sup -1^ of pp collision data collected by the LHCb experiment at ... TeV in 2011. The CP asymmetry between the B ^sup 0^ [arrow right] DK ^sup 0^ and the ... decay rates, with the neutral D meson in the CP-even final state K ^sup +^ K ^sup -^, is found to be...where the first uncertainty is statistical and the second is systematic. In addition, favoured B ^sup 0^ [arrow right] DK ^sup 0^ decays are reconstructed with the D meson in the non-CP eigenstate K ^sup +^[pi]^sup -^. The ratio of the B-flavour averaged decay rates in D decays to CP and non-CP eigenstates is measured to be...where the ratio of the branching fractions of D ^sup 0^ [arrow right] K ^sup -^[pi]^sup +^ to D ^sup 0^ [arrow right] K ^sup +^ K ^sup -^ decays is included as multiplicative factor. The CP asymmetries measured with two control channels, the favoured B ^sup 0^ [arrow right] DK ^sup 0^ decay with D [arrow right] K ^sup +^[pi]^sup -^ and the ... decay with D[arrow right]K ^sup +^ K ^sup -^, arealsoreported.[Figure not available: see fulltext.]
