Heavy Flavour Physics at the LHC

A summary of results in heavy flavour physics from Run 1 of the LHC is presented. Topics discussed include spectroscopy, mixing, CP violation and rare decays of charmed and beauty hadrons.Comment: 25 pages, 9 figures (total 17 subfigures). Invited review for Comptes Rendus de Physique de l'Academie des Science

Silicon Tracker zero-suppressed data model and decoding

The Silicon Tracker zero-suppressed data model and decoding are described. Examples of the use of the event model classes together with checks made of the data integrity in the decoding procedure are described

Interaction of point sources and vortices for incompressible planar fluids

We consider a new system of differential equations which is at the same time gradient and locally Hamiltonian. It is obtained by just replacing a factor in the equations of interaction for N point vortices, and it is interpreted as an interaction of N point sources. Because of the local Hamiltonian structure and the symmetries it obeys, it does possess some of the first integrals that appear in the N vortex problem. We will show that binary collisions are easily blown up in this case since the equations of motion are of first order. This method may be easily generalized to the blow up of higher order collisions. We then generalize the model further to interactions of sources and vortices.Comment: 9 page

Alignment of the Inner Tracker Stations Using First Data

Data taken during LHC synchronisation tests in August--September 2008 has been used to align the Inner Tracker ladders with a precision of 20,$mu$m. To validate the results, simulation studies with a high multiplicity particle gun have been performed. In addition, alignment studies with data taken with a cosmic trigger are discussed

Identification of Ghost Tracks using a Likelihood Method

The implementation of an algorithm based on a likelihood method to discriminate between real and ghost tracks is described. This algorithm is shown to perform slightly better than a cut on the $\chi^2$/ndof
