Optimization of the LHCb track reconstruction / Storaci, Barbara (Physik-Institut, Universität Zürich, Zürich, Switzerland)
The LHCb track reconstruction uses sophisticated pattern recognition algorithms to reconstruct trajectories of charged particles. Their main feature is the use of a Hough- transform like approach to connect track segments from different sub-detectors, allowing for having no tracking stations in the magnet of LHCb. [...]

Real-time alignment and calibration of the LHCb Detector in Run II / Dujany, Giulio (School of Physics and Astronomy, University of Manchester, Manchester, United Kingdom) ; Storaci, Barbara (Physik-Institut, Universität Zürich, Zürich, Switzerland)
table, precise spatial alignment and PID calibration are necessary to achieve optimal detector performance. During Run2, LHCb will have a new real-time detector alignment and calibration to allow equivalent performance in the online and offline reconstruction to be reached. [...]

Measurement of $CP$-Violating Phases in $B$ Decays at LHCb / Hussain, Nazim (University of Oxford, United Kingdom)
A selection of recent LHCb results pertaining to measurements of the CKM unitarity triangle are presented. In these proceedings, I summarise a measurement of $\sin(2\beta)$, the most precise time-dependent $CP$ violation measurement made at a hadron collider yet, as well as the latest LHCb $\gamma$ combination, a measurement of greater precision than the $B$ factories. [...]

Study of photon reconstruction efficiency using $B^+\to J/\psi K^{(*)+}$ decays in the LHCb experiment / Govorkova, Ekaterina (Institute of Theoretical and Experimental Physics (ITEP), Moscow, Russia)
The reconstruction efficiency of photons and neutral pions is measured using the relative yields of reconstructed $B^+\to J/\psi K^{*+} (\to K^+\pi^0)$ and $B^+\to J/\psi K^+$decays. The efficiency is studied using the data set, corresponding to an integrated luminosity of $3~\mathrm{fb}^{-1}$, collected by the LHCb experiment in proton-proton collisions at the centre-of-mass energies of 7 and 8 $TeV$..

CP violation measurements at the LHCb experiment / Pescatore, Luca (University of Birmingham, Birmingham, United Kingdom)
Decays of b-hadrons are the ideal place to perform measurements of CP violation. Many decay channels allow to over-constrain the unitarity triangles of the CKM matrix and test the SM hypothesis that a single phase is the origin of all CP violation. [...]

Rare decays at the LHCb experiment / Pescatore, Luca (University of Birmingham, Birmingham, United Kingdom)
Rare decays of beauty and charm hadrons offer a rich playground to make precise tests of the Standard Model and look for New Physics at the level of quantum corrections. A review of recent LHCb results will be presented..

An analysis of $\Lambda_b^0 \rightarrow \Lambda\mu^+\mu^-$ decays at the LHCb experiment / Pescatore, Luca (University of Birmingham, GB)
The branching fraction of the rare decay $\Lambda_b^0 \rightarrow \Lambda \mu^+ \mu^-$ is measured as a function of $q^2$, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb$^{-1}$, collected by the LHCb experiment. [...]

Evaporative CO$_2$ microchannel cooling for the LHCb VELO pixel upgrade / de Aguiar Francisco, Oscar A (Universidade Federal do Rio de Janeiro (UFRJ), Rio de Janeiro, Brazil) ; Buytaert, Jan (CERN, Geneva, Switzerland) ; Collins, Paula (CERN, Geneva, Switzerland) ; Dumps, Raphael (CERN, Geneva, Switzerland) ; John, Malcolm (Department of Physics, University of Oxford, Oxford, United Kingdom) ; Mapelli, Alessandro (CERN, Geneva, Switzerland) ; Romagnoli, Giulia (CERN, Geneva, Switzerland)
The LHCb Vertex Detector (VELO) will be upgraded in 2018 to a lightweight pixel detector capable of 40 MHz readout and operation in very close proximity to the LHC beams. The thermal management of the system will be provided by evaporative CO$_2$ circulating in microchannels embedded within thin silicon plates. [...]

Measuring Semileptonic Asymmetries in LHCb / Klaver, Suzanne (School of Physics and Astronomy, University of Manchester, Manchester, United Kingdom)
The $CP$-violating flavour-specific asymmetry in neutral $b$ mesons provides a method for testing the Standard Model. The measurements from the D0 experiment yield values of this asymmetry that disagree with the Standard Model at a level of 3.6 $\sigma$. [...]
