 Novel real-time alignment and calibration of the LHCb detector in Run II / Xu, Zhirui (Ecole Polytechnique Federale de Lausanne (CH)) ; Tobin, Mark (Ecole Polytechnique Federale de Lausanne (CH)) An automatic real-time alignment and calibration strategy of the LHCb detector was developed for the Run II. Thanks to the online calibration, tighter event selection criteria can be used in the trigger. [...] LHCb-PROC-2016-007; CERN-LHCb-PROC-2016-007.- Geneva : CERN, 2015 - 2.

 Electroweak penguin B decays / Nikodem, Thomas (Ruprecht-Karls-Universitaet Heidelberg (DE)) Flavour Changing Neutral Currents (FCNC) are sensitive probes for physics beyond the Standard Model (SM), so-called New Physics. An example of a FCNC is the $b \to s$ quark transition described by the electroweak penguin Feynman diagram shown in Figure 1.

 Preparation and commissioning of LHCb for the Run II of LHC / Puig Navarro, Albert (Ecole Polytechnique Federale de Lausanne (CH)) The LHCb experiment has performed very well during the Run I of the LHC, producing a large number of relevant physics results on a wide range of topics. The preparation and commissioning of the LHCb experiment for Run II is discussed here, with special emphasis on the changes in the trigger strategy and the addition of a new subdetector to improve the physics reach of the experiment.

 The LHCb Turbo stream / Puig Navarro, Albert (Ecole Polytechnique Federale de Lausanne (CH)) The LHCb experiment will record an unprecedented dataset of beauty and charm hadron decays during Run II of the LHC, set to take place between 2015 and 2018. A key computing challenge is to store and process this data, which limits the maximum output rate of the LHCb trigger. [...] LHCb-PROC-2016-004; CERN-LHCb-PROC-2016-004.- Geneva : CERN, 2016 - 2.

 Review of recent LHCb results and expectations for Run II / Hicheur, Adlene (Univ. Federal do Rio de Janeiro (BR)) As first Run II data acquisition has begun, it is useful to expose the pending questions by reviewing some of the most recent results obtained with Run I data analyses. Early results of the current data taking and middle-term prospects are also shown to illustrate the efficiency of the acquisition and analysis chain..

 Selection of LHCb results from Run I / Hicheur, Adlene (Univ. Federal do Rio de Janeiro (BR)) At the eve of the second LHC data taking run, some of the most recent results obtained by the LHCb collaboration with Run I data are reviewed. Improved measurements on $CP$ violation, unitary triangle and mixing parameters are shown. [...] LHCb-PROC-2016-002; CERN-LHCb-PROC-2016-002.- Geneva : CERN, 2016 - 7.

 LHCb early measurements focusing on B and charm production / Pearce, Alex (University of Manchester (GB)) Measurements of the production cross-sections of prompt $J/\psi$, $D^{0}$, $D^{+}$, $D_{s}^{+}$, and $D^{*+}$ mesons are presented, using proton-proton collision data taken at a centre-of-mass energy of $\sqrt{s} = 13\,\text{TeV}$ with the LHCb detector. The cross-section measurements are made in bins of meson transverse momentum $p_{\text{T}}$ and rapidity $y$, up to a $p_{\text{T}}$ of $14\,\text{GeV}$ for the $J/\psi$ measurements and $15\,\text{GeV}$ for the open charm meson measurements, both in the rapidity range $2.0 < y < 4.5$.

 Measurement of $J/\psi$ production cross-section in pp collisions at $\sqrt{s}=13$TeV at LHCb / Komarov, Ilya (Ecole Polytechnique Federale de Lausanne (CH)) The production of $J/\psi$\ mesons in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$TeV is studied with the LHCb detector. Cross-section measurements are performed as a function of the transverse momentum $p_{\rm T}$ and the rapidity $y$ of the $J/\psi$ meson in the region $\mbox{$p_{\rm T}$}<14$GeV/$c$ and $2.0 < y < 4.5$, for both prompt $J/\psi$ mesons and $J/\psi$ mesons from $b$-hadron decays.

 Searches for Majorana Neutrinos and Direct Searches for Exotics at LHCb / Cid Vidal, Xabier (CERN) These proceedings present the LHCb results on Majorana neutrino searches and direct production of exotic particles using the data collected during Run I of LHC. For the former, Majorana neutrinos are searched for both on-shell and off-shell in $B$ and $D$ decays to final states with two same-sign muons.
