The Timepix3 Telescope andSensor R&D for the LHCb VELO Upgrade / Dall'Occo, Elena (Nikhef National institute for subatomic physics (NL))
The VErtex LOcator (VELO) of the LHCb detector is going to be replaced in the context of a major upgrade of the experiment planned for 2019-2020. The upgraded VELO is a silicon pixel detector, designed to with stand a radiation dose up to $8 \times 10^{15} 1 ~\text {MeV} ~\eta_{eq} ~ \text{cm}^{−2}$, with the additional challenge of a highly non uniform radiation exposure.

Recent LHCb results in charm spectroscopy / He, Jibo (University of Chinese Academy of Sciences (CN))
LHCb continues to expand its world-leading sample of charmed hadrons collected during LHC's Run 1 and Run 2. With this data set, LHCb is discovering many previously unobserved charmed states and making the most precise determinations of the properties of these states. [...]

Studies of $B_c$ mesons at LHCb / He, Jibo (University of Chinese Academy of Sciences (CN))
The $B_c$ meson is formed by two heavy quarks of different flavor, which makes it an interesting laboratory for test of effective theories of the strong interaction with a unique setting for production, decay and spectroscopy studies. This paper presents recent results on the $B_c$ meson from LHCb, including the $B_c^+$ mass, lifetime and production measurements, search for excited $B_c^+$ states, observation of the $B_c^+\to D^0 K^+$ decay, and search for $B_c^+$ decays to two charm mesons..

Time dependent CPV in the beauty sector / Benson, Sean (Nikhef National institute for subatomic physics (NL))
Time-dependent $CP$ violating phenomena probe the time evolution and the decay of beauty hadrons and allow access to the underlying dynamics. We present various time-dependent $CP$ violation measurements in the $B^0$ and $B_s^0$ meson systems that are performed using $pp$ collisions by LHCb and using $e^{+}e^{-}$ collisions by the B factory experiments BaBar and Belle [...]

Strategy and Automation of the Quality Assurance Testing of MaPMTs for the LHCb RICH Upgrade / Gizdov, Konstantin (The University of Edinburgh (GB))
The LHCb RICH system will undergo major modifications for the LHCb Upgrade during the Long Shutdown 2 of the LHC, and the current photon detectors will be replaced by Multi Anode PMTs. The operating conditions of the upgraded experiment puts forth significant requirements onto the MaPMTs in terms of their performance, durability \& reliability. [...]

Measurement of CP Violation in $B_s^0 \to J\psi \phi$ decays / Gizdov, Konstantin (The University of Edinburgh (GB))
Precise measurements of CP violation provide stringent tests of the Standard Model towards a search for signs of New Physics. The decay-time dependent CP asymmetry in $B_s^0 \to J\psi \phi$ decays has been measured using proton-proton, $pp$, collision data, collected with the LHCb detector. [...]

LHCb full-detector real-time alignment and calibration: latest developments and perspectives / Dziurda, Agnieszka (Polish Academy of Sciences (PL)) ; Mogini, Andrea (Centre National de la Recherche Scientifique (FR))
The LHCb detector is a single-arm forward spectrometer, which measures proton-proton inter- actions at the LHC. For Run II (2015-2018) LHCb has introduced a novel real-time detector alignment and calibration strategy. [...]
