LHCb Run 2 Trigger Performance / Sciascia, Barbara (Istituto Nazionale Fisica Nucleare Frascati (IT))
During the first long shutdown of the LHC (2013-2014, LS1), the LHCb detector remained essentially unchanged, while the trigger system has been completely revisited. Upgrades to the LHCb computing infrastructure have allowed for high quality decay information to be calculated by the software trigger making a separate offline event reconstruction unnecessary [...]

Machine learning and parallelism in the reconstruction of LHCb and its upgrade / De Cian, Michel (Ruprecht-Karls-Universitaet Heidelberg (DE))
The LHCb detector at the LHC is a general purpose detector in the forward region with a focus on reconstructing decays of c- and b-hadrons. For Run II of the LHC, a new trigger strategy with a real-time reconstruction, alignment and calibration was employed. [...]

B decays to open charm / Haines, Susan Carol (University of Cambridge (GB))
Studies of $B$ meson decays to states involving open charm mesons in data recorded by the LHCb experiment have resulted in first observations of several new decay modes, including $B_s^{0} \rightarrow D_s^{*\mp} K^{\pm}$, $B_s^{0} \rightarrow \overline{D}^{0} K_S^{0}$ and $B^{+} \rightarrow D^{+} K^{+} \pi^{-}$ decays. An upper limit has been placed on the branching fraction of $B_s^{0} \rightarrow \overline{D}^{0} f_0(980)$ decays. [...]

Multibody charmless b-hadron decays / Dujany, Giulio (University of Manchester (GB))
Multibody charmless b-hadron decays are a unique laboratory to probe CP violation, to look for effects of new physics and to provide insights into the hadronisation mechanism. The decay modes $\Lambda_b^0 \to \Lambda K^+ K^-$, $\Lambda_b^0 \to \Lambda K^+ \pi^-$, $\Lambda_b^0 \to \Lambda \phi$ and $B_s^0 \to K_{\rm S}^0 K^*$ are observed for the first time by LHCb and their branching fractions are measured.

Timing and Readout Contorl in the LHCb Upgraded Readout System / Alessio, Federico (CERN)
In 2019, the LHCb experiment at CERN will undergo a major upgrade where its detectors electronics and entire readout system will be changed to read-out events at the full LHC rate of 40 MHz. In this paper, the new timing, trigger and readout control system for such upgrade is reviewed [...]

LHCb results on 13 TeV $pp$ collisions / Alessio, Federico (CERN)
By using the very first proton-proton collision data of the LHC Run II, the LHCb experiment performed a series of early measurements, including the cross-sections for quarkonia, beauty and charm productions. The results have been carried out by exploiting a new scheme for the LHCb software trigger, where the algorithm has been split in two stages [...]

Results of heavy ion collisions at LHCb / Zhang, Yanxi (Laboratoire de l'Accelerateur Lineaire (FR))
Heavy flavor production is important in heavy ion collisions to study both cold and hot nuclear matter effects. The LHCb experiment can make unique contribution to heavy ion physics, owing to the full particle identification of the detector in the forward region and the ability to collect fixed target data with proton or lead beams.

CP violation in b-hadrons / Benson, Sean (Nikhef National institute for subatomic physics (NL))
Latest LHCb measurements of $CP$ violation in b-hadrons are presented based on $pp$ collision data collected in 2011 and 2012 at centre-of-mass energies of $\sqrt{s}=7$ $\rm TeV$ and $8\ \rm TeV$ respectively. The total integrated luminosity collected is 3.0 fb$^{-1}$. [...]
