 $\phi_s$ 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. [...] LHCb-PROC-2019-013; CERN-LHCb-PROC-2019-013.- Geneva : CERN, 2019 - 8.

 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 [...] LHCb-PROC-2019-011; CERN-LHCb-PROC-2019-011.- Geneva : CERN, 2019 - 8.

 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.

 Soft QCD and Central Exclusive Production at LHCb / Kucharczyk, Marcin (Cracow, INP) /LHCb Collaboration The LHCb detector, owing to its unique acceptance coverage $(2 < \eta < 5)$ and a precise track and vertex reconstruction, is a universal tool allowing the study of various aspects of electroweak and QCD processes, such as particle correlations or Central Exclusive Production. The recent results on the measurement of the inelastic cross section at $\sqrt s = 13 \ \rm{TeV}$ as well as the Bose-Einstein correlations of 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 $\sqrt s = 7\ \rm{and} \ 8 \ \rm{TeV}$, are summarized in the present proceedings, together with the studies of Central Exclusive Production at $\sqrt s = 13 \ \rm{TeV}$ exploiting new forward shower counters installed upstream and downstream of the LHCb detector.

 Tests of Lepton Flavour Universality at LHCb / Mueller, Katharina (Universitaet Zuerich (CH)) In the Standard Model of particle physics the three charged leptons are identical copies of each other, apart from mass differences, and the electroweak coupling of the gauge bosons to leptons is independent of the lepton flavour. This prediction is called lepton flavour universality (LFU) and is well tested. [...] LHCb-PROC-2019-006; CERN-LHCb-PROC-2019-006.- Geneva : CERN, 2019 - mult.p.

 Mixing and time-dependent CP violation in beauty at LHCb / Govorkova, Katya (Nikhef National institute for subatomic physics (NL)) Recent measurements of the time-dependent CP violation are presented. The decays of $B_{s}^{0}$ mesons to $J/\psi\,K^+ K^-$ and $J/\psi\,\pi^+ \pi^-$ final states are used to measure CP-violating parameters with proton-proton collision data, corresponding to an integrated luminosity of 1.9 fb$^{-1}$, collected by the LHCb detector at a centre-of-mass energy of 13 TeV in 2015 and 2016 [...] LHCb-PROC-2019-005; CERN-LHCb-PROC-2019-005.- Geneva : CERN, 2019 - mult.p.
