This thesis presents a world-first measurement of the CP parameters of B0s -> Dsπ with the aim of testing the flavour-specific nature of the decay. The measurement is made using ∫L = 1.0 fb−1 of pp collisions recorded at a centre-of-mass energy of √s = 7TeV collected during 2011. The measured values of the CP parameters are S = 0.197 ± 0.150 ± 0.025, D = −0.888 ± 0.098 ± 0.541, ΔS = 0.066 ± 0.083 ± 0.004, ΔD = −0.062 ± 0.050 ± 0.169, where the first uncertainties are statistical and the second are systematic. These results are consistent with the Standard Model prediction. A measurement of the CP parameters of B0s -> DsK is also presented, producing C = 1.01 ± 0.50 ± 0.23, Sf = −1.25 ± 0.56 ± 0.24, Sf = 0.08 ± 0.68 ± 0.28, Df = −1.33 ± 0.60 ± 0.26, Df = −0.81 ± 0.56 ± 0.26, where the first uncertainties are statistical and the second are systematic.
