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

Momentum scale calibration using resonances
The use of resonances to calibrate the momentum scale is discussed. Formula for the relationship between the magnetic field scale and the measured mass are derived and applied to the decays J/, \ks and
Combined Long Tracking Performance
The performance of the track reconstruction for `Long Tracks' in DC'~06 is presented in detail. An event weighted efficiency of 89.4 % is found for a ghost rate of 16.7 %
Classification of Ghost Tracks
A tool for classifying ghost tracks together with the results obtained with Brunel v31r8 is described
Performance of the Track Matching
The performance of the track matching algorithm in Brunel v31r8 is discussed. An event weighted efficiency of is found for a ghost rate of
Clone Track Identification using the Kullback-Liebler Distance
The implementation and performance of an algorithm that identifies and removes clone tracks using the Kullback-Liebler distance is discussed. For long tracks this algorithm reduces the clone rate to the level of 3 per mille for a 2 per mille loss in efficency
The Tsa Reconstruction Framework
The classes comprising the Tsa reconstruction framework at the time of Brunel v31r1 are described together with their use
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 /ndof
Performance of the LHCb Track Reconstruction Software
Abstract The performance of the LHCb track reconstruction software at the time of the DC 06 re-processing is described. For Long Tracks an event weighted efficiency of is found for a ghost rate of . For these tracks a momentum resolution of per mille is obtained after a Kalman filter based fit
