Optimization of the Muon Identification software for LHCb Run II / Albrecht, Johannes (Technische Universitaet Dortmund (DE)) ; Dettori, Francesco (University of Liverpool (GB)) ; Dungs, Kevin (CERN) ; Lopes, Helder (Univ. Federal do Rio de Janeiro (BR)) ; Martinez Santos, Diego (Universidade de Santiago de Compostela (ES)) ; Prisciandaro, Jessica (Universidade de Santiago de Compostela (ES)) ; Sciascia, Barbara (Istituto Nazionale Fisica Nucleare Frascati (IT)) ; Syropoulos, Vasileios (Nikhef National institute for subatomic physics (NL)) ; Vazquez Gomez, Ricardo (Istituto Nazionale Fisica Nucleare Frascati (IT))
The muon identification code in the LHCb HLT software trigger and offline reconstruction has been revisited in view of the LHC Run 2. This software has undergone a significant refactorisation, resulting in a modularized common code base between the HLT and offline event processing [...]

Upgrade trigger: Bandwidth strategy proposal / Boettcher, Thomas Julian (Massachusetts Inst. of Technology (US)) ; Fitzpatrick, Conor (Ecole Polytechnique Federale de Lausanne (CH)) ; Meloni, Simone (Universita & INFN, Milano-Bicocca (IT)) ; Whitehead, Mark Peter (CERN) ; Williams, Mark Richard James (University of Manchester (GB))
This document describes a proposed selection strategy for the upgrade trigger using charm signals as a benchmark. The Upgrade trigger uses a 'Run2-like' sequence consisting of a first and second stage, in between which the calibration and alignment is performed. [...]

Upgrade trigger: Biannual performance update / Aaij, Roel (CERN) ; Albrecht, Johannes (Technische Universitaet Dortmund (DE)) ; Couturier, Ben (CERN) ; Esen, Sevda (Ruprecht-Karls-Universitaet Heidelberg (DE)) ; De Cian, Michel (Ruprecht-Karls-Universitaet Heidelberg (DE)) ; Dziurda, Agnieszka (CERN) ; Fitzpatrick, Conor (Ecole Polytechnique Federale de Lausanne (CH)) ; Fontana, Marianna (Universita e INFN, Cagliari (IT)) ; Grillo, Lucia (Universita & INFN, Milano-Bicocca (IT)) ; Hasse, Christoph (Technische Universitaet Dortmund (DE)) et al.
This document presents the performance of the LHCb Upgrade trigger reconstruction sequence, incorporating changes to the underlying reconstruction algorithms and detector description since the Trigger and Online Upgrade TDR. An updated extrapolation is presented using the most recent example of an Event Filter Farm node..

A Track Matching Algorithm for the LHCb upgrade / Esen, Sevda (Ruprecht-Karls-Universitaet Heidelberg (DE)) ; De Cian, Michel (Ruprecht-Karls-Universitaet Heidelberg (DE))
This document presents a description and performance estimate of the Track Matching algorithm for the LHCb Upgrade. The algorithm combines tracks reconstructed in the Vertex Locator and in the three stations of the Scintillating Fibre Tracker..

Shear and Thermal Testing of Adhesives for VELO Upgrade / De Capua, Stefano (University of Manchester (GB)) ; Freestone, Julian (University of Manchester (GB)) ; Klaver, Suzanne (University of Manchester (GB)) ; Parkes, Chris (University of Manchester (GB)) ; Rodriguez Perez, Pablo (University of Manchester (GB)) ; Shtipliyski, Antoni (Imperial College (GB)) ; Stelmasiak, Guy James (University of Manchester (GB))
As part of the R&D; process of the LHCb VELO Upgrade, a study has been performed on the thermal and mechanical performance of the adhesives Stycast 2850FT, 3M 9461P, and Araldite 2011. One or more of these adhesives could be used to attach the ASICs and hybrids to the microchannel cooling substrate. [...]

Synergy of BESIII and LHCb physics programmes / Malde, Sneha Sirirshkumar (University of Oxford (GB))
There is potential for BESIII open-charm measurements to have a significant impact on the LHCb physics programme. Despite the general purpose design of the LHCb detector there are certain inputs that can be better determined in other environments or in production mechanisms not accessible at the LHC. [...]
