Measurement of CP Violation in B 0 d Mixing Using B 0 d → D *- μ + (ν μ )X Decays

This thesis describes the measurement of the time-integrated semileptonic charge asymmetry in B 0 d mixing, a d sl , using the decay chain of B 0 d ! D *- μ + (ν μ ), D *- ! D 0 π - , D 0 ! K + π - . Decay candidates are reconstructed from 10.4 fb -1 of data recorded by the DØ detector at Fermilab’s Tevatron p$\bar{p}$ collder during the 2002- 2011 ‘RunII’ data taking period. Yields are extracted using a 2 minimising simultaneous binned fit where 490k D candidates are reconstructed. The measurements presented in this thesis was made possible due to sophisticated online and offline reconstruction software, precise tracking systems, and the first-order background asymmetry negating magnet polarity reversal of the DØ detector.
