LHCb: A Large Hadron Collider Beauty Experiment for Precision Measurements of CP-Violation and Rare Decays

The LHCb experiment is the forward arm spectrometer at the LHC. It is a optimised precision measurements of CP violation and rare decays in the b quark sector. Recent experimental results have shown that CP violation is large in this sector.
Talks and Notes
Controlling Penguin contributions

I collaborate with Kristof de Bruyn and Robert Fleischer on the channel Bs→J/ψKS which is (weakly) sensitive to γ and is a control for penguin effects affecting the measurement of β in Bd→J/ψKS.

We recently measured its branching fraction with 0.4 fb-1. Links:

This triggered a collaboration between experimentalists and theorists:

Penguin Decays

I am participating in the analysis of rare semileptonic decays, in particular B → μμK* and B → llK. I am proud to be able to report the observation of the very rare decay B → μμK at LHCb with 37 pb-1.

Operations I am the operations coordinator, overseeing all aspects of data collection and processing from trigger to physics processing. I am also the deputy physics coordinator.
High Level Trigger

I used to be developing the HLT... but don't have time any more.
