 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.

 Searches for Higgs and Higgs-like particles at LHCb / Kucharczyk, Marcin (Polish Academy of Sciences (PL)) A set of results related to the new particles searches in LHCb are reported. Upper limits on the cross section times branching fraction of neutral Higgs boson decaying into two tau leptons have been set in the model independent search and in the Minimal Supersymmetric Model.

 $CP$ violation and CKM studies (and first LHCb Run II results) / Koppenburg, Patrick (Nikhef National institute for subatomic physics (NL)) The LHC is the new $b$-hadron factory and will be dominating flavour physics until the start of Belle II, and beyond in many decay modes. While the $B$ factories and Tevatron experiments are still analysing their data, ATLAS, CMS and LHCb are producing interesting new results in $CP$ violation and rare decays, that set strong constraints on models beyond that SM and exhibit some discrepancies with the SM predictions.

 Results from $pPb$ collisions and prospects for heavy-ion interactions with LHCb / Schmidt, Burkhard (CERN) The forward acceptance of the LHCb detector allows to probe proton and ion collisions in a unique kinematic range, complementary to the other LHC experiments. In the first part of these proceedings the production of $J/\psi$ and $\Upsilon$ mesons decaying into two muons is presented.

 Studies of particle production in pp collisions in the forward region at LHCb / Schmidt, Burkhard (CERN) The LHCb detector at the LHC has a pseudorapidity coverage $(2 < \eta < 5)$ which allows it to perform particle production measurements in a kinematic region where QCD models have large uncertainties. Selected analyses on particle production measurements in $pp$ collisions are summarised in these proceedings. [...] LHCb-PROC-2015-027; CERN-LHCb-PROC-2015-027.- Geneva : CERN, 2015 - 4.

 Heavy flavor production in the forward acceptance at the LHC / Polyakov, Ivan (Moscow, ITEP) In this report the most recent results on heavy flavor production studies at the LHCb experiment are covered. The measurements of production cross-sections of the $\chi_{bJ}({\rm mP})$, $\eta_{c}({\rm 1S})$ and $B_c^+$ states in proton-proton collisions at center of mass energies $\sqrt{s}=$7 and 8 TeV are presented..

 $CP$ Violation in $B$ Decays at LHCb A selection of recent results from studies of $C\!P$ violation in the decays of $B$ mesons are presented, which were performed using $pp$ collision data at $\sqrt{s}=7$ TeV and 8 TeV collected by the LHCb experiment during Run I, corresponding to an integrated luminosity of 3.0 fb$^{-1}$..

 Novel real-time alignment and calibration of the LHCb detector in Run II Stable, precise spatial alignment and PID calibration are necessary to achieve optimal detector performance. During Run II, LHCb will have a new real-time detector alignment and calibration to allow equivalent performance in the online and offline reconstruction to be reached.
