By Paolo Gandini

CP violation is a well-established phenomenon in particle physics, yet until eventually 2001 it used to be simply saw in kaons. within the final decade, numerous matter-antimatter asymmetries were saw in impartial B mesons in accordance with the expectancies of the normal version of the vulnerable interaction.  Direct CP violation can be anticipated within the decay premiums of charged B+ mesons as opposed to that of B- mesons, although the best results are found in a decay that happens simply two times in 10 million decays. Such rarity calls for large samples to review and this is often precisely what the LHC, and its committed B-physics scan LHCb provide. This thesis presents an analysis of the 1st years of LHCb data. The author describes the 1st statement of the infrequent decay, B- → DK-, D → π-K+ and the 1st remark of direct CP violation during this B decay. The work constitutes crucial details at the experiment’s size of a basic parameter of the idea and stands as a benchmark opposed to which next analyses of this kind might be compared.
