 Heavy-ion physics and strong interactions at LHCb / Dembinski, Hans Peter (Technische Universitaet Dortmund (DE)) The LHCb experiment is a single-arm spectrometer designed for the study of heavy flavour physics at the LHC, but also an excellent general purpose experiment for the study of quantum chromodynamics in the forward region. The forward acceptance make the LHCb data particular interesting for many applications in astroparticle physics, which are dominated by forward hadron production.

 Precision Measurement of the $B_s-\kern0.18em\overline{\kern -0.18em B}{}^0_s$ Oscillation Frequency $\Delta m_s$ with $B_s\to D_s^-\pi^+$ Decays at LHCb / Heinicke, Kevin (Technische Universitaet Dortmund (DE)) /LHCb Collaboration Decays of $B^0_s \to D_s^- \pi^+$ allow to determine the oscillation frequency $\Delta m_s$ between the $B^0_s$ particle and $\kern0.18em\overline{\kern -0.18em B}{}^0_s$ antiparticle states with high precision. It is a crucial input to constrain the CKM matrix and a manifestation of the quantum nature of physics.

 Rare decays and searches for exotic signatures at LHCb: purely leptonic decays / Mombacher, Titus (Universidade de Santiago de Compostela (ES)) A review of the experimental status of purely leptonic ${B^0_{[s]}\to\ell^+\ell^-}$ decays is given and the new analysis of ${B^0_{[s]}\to\mu^+\mu^-}$ observables with the LHCb experiment is presented. The new results are the most precise single experiment measurements of the quantities to date and are consistent with the Standard Model.

 Studies of b-hadrons at LHCb / Matiunin, Slava (NRC "Kurchatov Institute" (ITEP) (RU)) /LHCb Collaboration A large data set collected at the LHCb experiment in proton-proton collisions during Runs 1 and 2 of the Large Hadron Collider has opened a unique possibility to study heavy beauty hadron states and to broaden knowledge of their spectroscopy and production. Recent results on searches for new excited $\mathrm{b}$-hadron states, and studies of $\mathrm{b}$-hadron production, are reviewed.
