Experimental status of LNU in B decays in LHCb / Benson, Sean (Nikhef National institute for subatomic physics (NL))
In the Standard Model, the three charged leptons are identical copies of each other, apart from mass differences. Experimental tests of this feature in semileptonic decays of b-hadrons are highly sensitive to New Physics particles which preferentially couple to the 2nd and 3rd generations of leptons. [...]

Rare radiative decays at LHCb / Puig Navarro, Albert (Universitaet Zuerich (CH))
Radiative $b$-hadron decays are sensitive probes of New Physics through the study of branching fractions, $CP$ asymmetries and measurements of the polarization of the photon emitted in the decay. During Run I of the LHC, the LHCb experiment has collected large samples of radiative $b$-hadron decays [...]

Simultaneous usage of the LHCb HLT farm for Online and Offline processing workflows
LHCb is one of the 4 LHC experiments and continues to revolutionise data acquisition and analysis techniques. Already two years ago the concepts of “online” and “offline” analysis were unified: the calibration and alignment processes take place automatically in real time and are used in the triggering process such that Online data are immediately available offline for physics analysis (Turbo analysis), the computing capacity of the HLT farm has been used simultaneously for different workflows : synchronous first level trigger, asynchronous second level trigger, and Monte-Carlo simulation.

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. [...]
