Due to a planned intervention the CERN Document Server website will be read only (no new submission or restricted content) from Tuesday, June 29th at 13:30 CEST to Wednesday, June 30th at 9:30 CEST.
The website will be shortly unavailable at the beginning and at the end of the intervention.

Selected HLT2 reconstruction performance for the LHCb upgrade /LHCb Collaboration
The throughput and performance of the HLT2 reconstruction is shown including track reconstruction efficiencies, fake rate and resolution, together with ECAL cluster reconstruction efficiency, resolution and electron PID. This document updates the previous report on the HLT2 throughput and physics performance documented in \href{https://cds.cern.ch/record/2715210}{LHCb-FIGURE-2020-007} and \href{https://cds.cern.ch/record/2715267}{LHCb-FIGURE-2020-008}, respectively..

Comparison of particle selection algorithms for the LHCb Upgrade /LHCb Collaboration
The CPU timing performance of several particle selection algorithms are shown in the context of the LHCb Upgrade trigger system. The algorithms are used to compare array-of-structure data models with structure-of-array models, and to compare scalar CPU instruction sets with the vector SSE and AVX2 instruction sets. [...]

LHCb $\gamma$ combination /LHCb Collaboration
The latest results from the LHCb $\gamma$ combination are presented for the 2020 LHCb Implications Workshop. New and updated inputs from $B^+ \to Dh^+$ ($D\to h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} K^+ \pi^-$), $B^+ \to D^*h^+$ ($D\to h^+h^-$), $B^0 \to D K^{*0}$ ($D\to h^+h^-$) and $B^0_s \to D^\mp_s K^\pm \pi^\mp \pi^\pm$ ($D^+_s \to h^+ h^- \pi^+$) decays are included.

LHCb calorimeter simulation using a library of energy deposits /LHCb Collaboration
We compare preliminary results from the fast simulation of the LHCb calorimeter, using a library of energy deposits, with the output from the nominal simulation based on Geant4. We describe the transformations applied to the energy deposits of the library to match the position and kinematic properties of the particle entering the calorimeter..
