Studies using B± → Dh± decays in the LHCb Run I data

Thesis

Using data equivalent to an integrated luminosity of 3 fb⁻¹ collected by the LHCb experiment during Run I (2011-2012), studies of beauty mesons decaying to a final state containing open charm are performed, concluding with a number of new results.

Direct CP-violation is explored in B^± → Dh^± decays through several measurements of CP violating observables, where the charmed meson D is reconstructed in both 2-track and 4-track final states. A measurement of the B^± production asymmetry at LHCb is reported using B^± → Dπ^± decays, and a complementary measurement of the CP asymmetry in B^± → J/ψK^± decays made. A search for the rare B_c− → D(*)π⁻ and B_c− → D (*)K⁻ decays concludes this work.
