LHCb has searched for the lepton flavour violating decay D0 ➝ e± μ∓ using 3 fb-1. This decay is forbidden in the standard model (SM) and so any observation of it would indicate new physics. The current world's best limit on B(D0 ➝ e± μ∓)<2.6×10-7 was set by the Belle collaboration at a 90% confidence level. The analysis is under working group review and hopes to improve upon Belle's limit. The analysis will be unblinded soon!
The mixing frequencies Δmd and Δms are measured using 1 fb-1 of semileptonic B decays and found to be 17.93 ± 0.27 and 0.503 ± 0.017, respectively.
The upgraded VELO detector was simulated using the full-LHCb simulations. The placement of the sensors along the z-axis was then optimised.
