 The Design and Construction of LHCb VELO Upgrades Modules / Svihra, Peter (University of Manchester (GB)) The LHCb experiment is a detector at the LHC designed to capture decays of b- and c-hadrons for the study of CP violation and rare decays. At the end of Run-II, many of the LHCb measurements remain statistically dominated. [...] LHCb-PROC-2020-005; CERN-LHCb-PROC-2020-005.- Geneva : CERN, 2020 - 6.

 Crystal Fibers for the LHCb Calorimeter Upgrade / Martinazzoli, Loris (Universita & INFN, Milano-Bicocca (IT)) The Large Hadron Collider beauty (LHCb) experiment is one of the four main particle detectors located at the Large Hadron Collider. After the high-luminosity upgrade of the accelerator, the expected radiation dose faced by the LHCb electromagnetic calorimeter will reach peak values of 1 MGy in the centermost part, an amount not tolerable by the currently employed Shashlik technology, which demands a novel radiation hard design.

 A new scheduling algorithm for the LHCb upgrade trigger application / Govorkova, Katya (Nikhef National institute for subatomic physics (NL)) ; Hasse, Christoph (Technische Universitaet Dortmund (DE)) ; Matev, Rosen (CERN) ; Nolte, Niklas Stefan (Technische Universitaet Dortmund (DE)) ; Ponce, Sebastien (CERN) ; Raven, Gerhard (Nikhef National institute for subatomic physics (NL)) ; Stahl, Sascha (CERN) During Run 3 of the LHC the LHCb detector will process a 30 MHz event rate with a full detector readout followed by a software trigger. To deal with the increased computational requirements, the software framework is reviewed and optimized on a large scale.

 $\phi_s$ status and prospects at LHCb / Govorkova, Katya (Nikhef National institute for subatomic physics (NL)) Recent measurements of the time-dependent CP violation by the LHCb experiment are presented. The decays of $B_s$ mesons to $J/\psi K^+ K^-$ and $J/\psi \pi^+ \pi^-$ final states are used to measure the CP-violating phase $\phi_{s}$ in tree-dominated transitions, while $B_s^0\to(K^+ \pi^-) (K^- \pi^+)$ and $B_s^0\to \phi \phi$ decay modes are used to measure the CP violating phases $\phi_{s}^{sd\overline{d}}$ and $\phi_{s}^{ss\overline{s}}$, which arise in penguin-dominated decays.

 Search for new decays of the $\Lambda_b^0$ baryon at the LHCb experiment. / Pereima, Dmitrii (NRC "Kurchatov Institute" (ITEP) (RU)) High statistics collected by the LHCb experiment between 2011 and 2018 in proton-proton (pp) collisions at the Large Hadron Colllider (LHC), jointly with the large cross-section of $b\bar{b}$ pairs production provides unique possibility for the search and study new decays of beauty hadrons. The results of search for new decays of the $\Lambda_b^0$ baryons are presented.

 B baryon decays at LHCb / Matiunin, Slava (NRC "Kurchatov Institute" (ITEP) (RU)) Large statistics collected by the LHCb experiment allows to study heavy baryons produced in proton-proton collisions at the Large Hadron Collider (LHC). Charmed and beauty hadrons produced in $pp$ collisions are studied to identify new states, confirming or disproving those recently claimed, and establishing their quantum numbers [...] LHCb-PROC-2019-012; CERN-LHCb-PROC-2019-012.- Geneva : CERN, 2019 - 6.

 Recent LHCb results on charm and charmonium spectroscopy / Matiunin, Slava (NRC "Kurchatov Institute" (ITEP) (RU)) The recent results on charm and charmonium spectroscopy obtained by the LHCb collaboration are reviewed. In particular, observation of new charmonium state in the decay modes $X(3842) \to D^0 \overline D{^{0}}$ and $\mathrm{X(3842)\rightarrow D^+ D^-}$ evidence for $\mathrm {\eta_c(1S)\pi^-}$ resonance in $\mathrm {B^0\rightarrow\eta_c(1S)K^+\pi^-}$ decay and observation of three narrow $\mathrm{P_c^+}$ pentaquark candidates decaying to $\mathrm{J/\psi p}$ are obtained.

 Gaussino - a Gaudi-Based Core Simulation Framework / Siddi, Benedetto Gianluca (Universita e INFN, Ferrara (IT)) ; Muller, Dominik (CERN) The increase in luminosity foreseen in the future years of operation of the Large Hadron Collider (LHC) creates new challenges in computing efﬁciency for all participating experiment. To cope with these challenges and in preparation for the third running period of the LHC, the LHCb collab- oration currently overhauls its software framework to better utilise modern computing architectures.

 TWO-PARTICLE CORRELATIONS AT THE LHCb∗ / Kucharczyk, Marcin (Polish Academy of Sciences (PL)) Due to its unique pseudorapidity coverage (2 < η < 5) and excellent performance, the LHCb detector allows the study of various aspects of par- ticle correlations at large rapidities and low transverse momenta. Selected results are summarized, such as the ﬁrst measurement of the Bose–Einstein correlations of the same-sign pions and kinematic correlations for pairs of beauty hadrons performed using large samples of proton–proton collision data accumulated with the LHCb detector at $\sqrt{s}$ = 7 and 8 TeV, together with the long-range correlations on the near side measured in proton–lead and lead–proton collisions at a nucleon–nucleon centre-of-mass energy of $\sqrt{s}$ = 5 TeV.
