CKM ANGLE GAMMA - Abstract
A first study of CP violation in the decay modes B-+/- -> [(KSK +/-)-K-0 pi(-/+)](D)h(+/-) and B-+/- -> [(KSK +/-)-K-0 pi(-/+)](D)h(+/-), where h labels a K or pi meson and D labels a D-0 or (D) over bar (0) meson, is performed. The analysis uses the LHCb data set collected in pp collisions, corresponding to an integrated luminosity of 3 fb(-1). The analysis is sensitive to the CP-violating CKM phase gamma through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of gamma using other decay modes. (C) 2014 The Authors. Published by Elsevier B.V.

[PHYS.HEXP]Physics [physics]/High Energy Physics - Experiment [hep-ex] ,Particle Physics - Experiment ,High Energy Physics - Experiment - Abstract
The resonant structure of the decay $\overline{B}_s^0\to J/\psi\pi^+\pi^-$ is studied using data corresponding to 3 fb$^{-1}$ of integrated luminosity from $pp$ collisions by the LHC and collected by the LHCb detector. Five interfering $\pi^+\pi^-$ states are required to describe the decay: $f_0(980),f_0(1500),f_0(1790),f_2(1270)$, and $f_2^{\prime}(1525)$. An alternative model including these states and a non-resonant $J/\psi \pi^+\pi^-$ component also provides a good description of the data. Based on the different transversity components measured for the spin-2 intermediate states, the final state is found to be compatible with being entirely $CP$-odd. The $CP$-even part is found to be $, Comment: 31 pages, 20 figures

[PHYS.HEXP]Physics [physics]/High Energy Physics - Experiment [hep-ex] ,Particle Physics - Experiment ,High Energy Physics - Experiment - Abstract
A search for the rare decay $D^0 \to \mu^+ \mu^-$is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb$^{-1}$, of $pp$ collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of events is consistent with the background expectations and corresponds to an upper limit of \mbox{${\cal B}(D^0 \to \mu^+ \mu^-) < 6.2(7.6) \times 10^{-9}$} at \mbox{90%} \mbox{(95%)} confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurements., Comment: 22 pages, 8 figures, Submitted to Physics Letters B

The LHCb experiment is one of the four main experiments at the Large Hadron Collider (LHC) at CERN. The LHCb detector is a one-arm spectrometer dedicated to precise measurements of the CP-violation and studies or rare b-hadron decays. The centre of mass energy and luminosity for a hadron collider) have both values never reached before. LHCb started data taking in November 2009. LHCb relies on excellent reconstruction and trigger efficiency, very good mass and proper time resolution, reliable particle identification systems to achieve the wanted precision on CP-violation parameters. These performances cannot be fulfilled without the detector to be calibrated. For instance, the Inner Tracker (IT) is readout by around a thousand chips, and the data are processed by 42 data acquisition cards, called TELL1. The Tracker Turicensis (TT) data are processed by 48 TELL1 boards. Each of these TELl1 boards has more than 18,000 parameters that need to be tuned in order to reduce the fake hits in the tracking systems. A high number of fake hits would result in poorer tracking performances. The first part of this thesis discuss the calibration of the IT and TT TELL1 boards. The first step was to find a way to extract the needed parameter values from data taken without beam. Once the parameters were gathered, a way to store them for future usage had to be found. The chosen solution was to use XML file, since XML files were already used for the detector geometry description and detector conditions. The XML file offered a convenient way to use the TELL1 parameters in the software framework, but those parameters were of course also required for data taking, i.e. they have to be uploaded to the TELL1 boards. A software library had to be developed in order to ‘translate’ the information contained in the XML file into a format handled by the control software. The second part discuss hit efficiency measurements in the IT. These measurements were shown to allow a monitoring of the detector status, as several hardware problems could be discovered by looking at the obtained efficiencies. Studies of the efficiency as a function of the clustering threshold allowed to improve background rejection in IT and TT by increasing one of the clustering thresholds. Finally, the last part covers the measurement of the B-meson lifetime in three decay channels: - $B^+ \to J/\psi(1S) (\mu^+\mu^-) K^+$, - $B^0 \to J/\psi(1S) (\mu^+\mu^-) K^{*0} (K^+\pi^-)$, - $B^0_s \to J/\psi(1S) (\mu^+\mu^-) \phi(1020) (K^+K^-)$. These values are already quite well known for $B^{\pm}$ and $B^0$, but their measurement represent a milestone in the measurement of the CP violating phase $\phi_s$ in the $B^0_s \to J/\psi \phi$ decay. Lifetime ratios are also presented: $\tau_{B^{\pm}}$ / $\tau_{B^0}$, $\tau_{B^0}$ / $\tau_{B^0_s}$ and $\tau_{B^+}$ / $\tau_{B^-}$. The first two allow to probe the Heavy Quark Effective Theory (HQET), whilst the last one is a test of CPT symmetry, foundation of the Quantum Field Theory.

- Abstract
The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The LHCb detector is a single-arm spectrometer with excellent tracking and particle identification capabilities. The Silicon Tracker is part of the tracking system and measures very precisely the particle trajectories coming from the interaction point in the region of high occupancies around the beam axis. The LHCb Silicon Tracker covers a total sensitive area of about 12 m(2) using silicon micro-strip technology. This paper reports on the operation and performance of the Silicon Tracker during the Physics data taking at the LHC. (C) 2012 Published by Elsevier B.V.
