Data analysis at the CMS level-1 trigger: migrating complex selection algorithms from offline analysis and high-level trigger to the trigger electronics
/ Wulz, Claudia (Vienna, OAW) ; Aradi, Gregor (Vienna, OAW) ; Arnold, Bernhard (Vienna, OAW) ; Bergauer, Herbert (Vienna, OAW) ; Ghete, Vasile M. (Vienna, OAW) ; Erö, Janos (Vienna, OAW) ; Jeitler, Manfred (Vienna, OAW) ; Rad, Navid (Vienna, OAW) ; Wittmann, Johannes (Vienna, OAW) ; Zarucki, Mateusz (Vienna, OAW)
/CMS Collaboration
With ever increasing luminosity at the LHC, optimum online data selection is becoming more and more important. While in the case of some experiments (LHCb and ALICE) this task is being completely transferred to computer farms, the others -- ATLAS and CMS -- will not be able to do this in the medium-term future for technological, detector-related reasons.

Global Trigger Upgrade firmware architecture for the level-1 Trigger of the CMS experiment
/ Rahbaran, Babak (Vienna, OAW) ; Arnold, B (Vienna, OAW) ; Bergauer, H (Vienna, OAW) ; Wittmann, J (Vienna, OAW) ; Matsushita, T (Vienna, OAW)
The Global Trigger (GT) is the final step of the CMS Level-1 Trigger and implements the ``menu'' of triggers, which is a set of selection requirements applied to the final list of objects (such as muons, electrons or jets) to trigger the readout of the detector and serve as basis for further calculations by the High Level Trigger. Operational experience in developing trigger menus from the first LHC run has shown that the requirements increased as the luminosity and pile-up increased. [...]

The Large Hadron Collider delivers up to 32 million physics collisions per second. This
rate is far too high to be processed by present-day computer farms, let alone stored on disk by the experiments for offline analysis [...]

Commissioning and performance of the CMS pixel tracker with cosmic ray muons
/ CMS Collaboration
The pixel detector of the Compact Muon Solenoid experiment consists of three barrel layers and two disks for each endcap. The detector was installed in summer 2008, commissioned with charge injections, and operated in the 3.8 T magnetic field during cosmic ray data taking. [...]
