This document describes the selection strategies for the upgrade trigger using a range of decay channels that are representative of the current, and planned, physics programme. The upgrade high-level trigger (HLT) follows the Run 2 trigger structure consisting of two stages, in between which the detector calibration and alignment is performed. [...]

LHCb Computing Resources: 2021 requests
/ Bozzi, Concezio (Universita e INFN, Ferrara (IT))
This document presents the computing resources needed by LHCb in 2021, the first year of data-taking with the upgraded LHCb detector. The computing requests are based on the Computing Model Technical Design Report for the LHCb Upgrade, with minor adjustments due to the update of the LHC running conditions..

LHCb Upgrades
/ Steinkamp, Olaf (Universitaet Zuerich (CH))
/LHCb Collaboration
During the LHC long shutdown 2, in 2019/2020, the LHCb collaboration is going to perform a major upgrade of the experiment. The upgraded detector is designed to operate at a five times higher instantaneous luminosity than in Run II and can be read out at the full bunch-crossing frequency of the LHC, abolishing the need for a hardware trigger. [...]

Search for the decay $B_s^0 \to D^{\ast +} D^{\ast -}$
/ Langer, Jan (Technische Universitaet Dortmund (DE)) ; Ibis, Philipp (Technische Universitaet Dortmund (DE)) ; Modden, Antje (Technische Universitaet Dortmund (DE))
A search for the decay $B_s^0 \to D^{\ast +} D^{\ast -}$ and the measurement of its branching ratio $\mathcal{BR}(B_s^0 \to D^{\ast +} D^{\ast -})$ relative to $\mathcal{BR}(B^0 \to D^{\ast +} D^{\ast -})$ is presented. The search is performed on data corresponding to 9\,$\text{fb}^{-1}$ of $pp$ collisions recorded by the LHCb experiment at a centre of mass energy of 7, 8\,TeV in 2011 to 2012 and 13\,TeV in 2015 to 2018 [...]
