The UCD School of Physics is a member institute of the CMS collaboration since 2002. The CMS collaboration consists of over 3000 physicists and engineers, building, operating and maintaining the CMS detector for data taking at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland.
The PI is Prof. Martin Grunewald, whose particle physics research interests with CMS lie in the precision measurements of top-quark and Higgs-boson properties produced in proton-proton collisions. In terms of experimental physics responsibilities for the CMS collaboration, he is convening the group responsible for integrating the High-Level Trigger (HLT) algorithms to form a comprehensive trigger menu ready for data taking. The trigger system in CMS consists of two parts, the Level-1 trigger (L1T) system, build from custom hardware and reducing the event rate from 40MHz to about 100kHz, and the HLT, running on a O(1000) cores CPU farm, and reducing the event rate further to a few hundred Hz.
UCD are authors and SFI is acknowledged on the Nobel prize-winning Higgs discovery paper (over 12,000 citations)
