Objective

The present matter-antimatter asymmetry of the universe cannot be explained by the Standard Model (SM) of particle physics. I propose to look for the presence of new physics beyond the SM in Charge-Parity (CP) asymmetries using beauty mesons decaying to charmed mesons (Beauty2Charm). A unique feature of these decays is that the SM contribution can be precisely measured using relations between ten decay modes all of which can be measured with in a coherent manner at a single experiment: LHCb at the Large Hadron Collier (LHC). The proposal will make measurements of ten branching ratios and eight analyses sensitive to CP violation using data collected by LHCb in order to test these relations. CP asymmetries larger than a few percent would be an unambiguous signal of the presence of new physics. In order to make these measurements at the required level of precision, I will lead a major upgrade to the way that the LHCb experiment selects proton proton collisions and for which I have laid the conceptual foundations. Real-Time Analysis will enable a dramatic increase in the the efficiency and signal yield of the decay modes relevant to this proposal, and reduce systematic uncertainties. To test and commission this upgrade I will lead the first ever measurements of beauty hadron production using final states without leptons. The experience gained in the commissioning phase will result in increased efficiencies for the CP sensitive channels leading to the world's most precise measurements and world-leading sensitivity to new physics.
