Description and performance of track and primary-vertex reconstruction with the CMS tracker / CMS Collaboration
A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices. Despite the very hostile environment at the LHC, the performance obtained with these algorithms is found to be excellent. [...]

Alignment of the CMS tracker with LHC and cosmic ray data / CMS Collaboration
The central component of the CMS detector is the largest silicon tracker ever built. The precise alignment of this complex device is a formidable challenge, and only achievable with a significant extension of the technologies routinely used for tracking detectors in the past. [...]

Luminosity Measurements with the ATLAS Detector / Maettig, Stefan
For almost all measurements performed at the Large Hadron Collider (LHC) one crucial ingredient is the precise knowledge about the integrated luminosity [...]

The Upgrade of the ATLAS Level-1 Central Trigger Processor / ANDERS, G (Ruprecht-Karls-Universitaet Heidelberg (DE)) ; BERGE, D (CERN) ; BERTELSEN, H (University of Copenhagen (DK)) ; DAM, M (University of Copenhagen (DK)) ; DOBSON, E (CERN) ; ELLIS, N (CERN) ; FARTHOUAT, P (CERN) ; GABALDON RUIZ, C (CERN) ; GHIBAUDI, M (CERN) ; GORINI, B (CERN) et al.
The ATLAS Level-1 Central Trigger Processor (CTP) combines information from calorimeter and muon trigger processors as well as other sources and makes the final Level-1 Accept (L1A) decision. Due to the increasing luminosity of the LHC and the growing demands of physics and monitoring placed on the ATLAS Level-1 trigger system, the current CTP has reached its design limits. [...]

An Upgraded ATLAS Central Trigger for 2014 Luminosities / Anders, G ; Berge, D ; Bertelsen, H ; Childers, T ; Dam, M ; Dobson, E ; Ellis, N ; Farthouat, P ; Gabaldon, C ; Gorini, B et al.
During 2011, the LHC reached instantaneous luminosities of 4*10^33 cm-2*s-1 and produced events with up to 24 interactions per colliding proton bunch. This places stringent operational and physical requirements on the ATLAS Trigger in order to reduce the 40MHz collision rate to a manageable event storage rate of ~400Hz and, at the same time, selecting those events considered interesting.

Measurement of the Luminosity by the ATLAS Experiment / Maettig, S (CERN/DESY)
This poster will present briefly the luminosity detectors in ATLAS and explain in some detail how they were used to extract and publish luminosity during the 2010 data taking. One of the challenges in measuring the luminosity at the LHC comes from the fact that many interactions typically occur in every bunch crossing. [...]
