Upgrading the LHCb trigger system

by Dorothea vom Bruch (LPNHE/CNRS), Vladimir Vava Gligorov (LPNHE/CNRS) , Alex Pearce (CERN), Sascha Stahl (CERN)

In the next run of the LHC (Run 3) the upgraded LHCb experiment will operate at a factor of five times the luminosty of the first run. The LHCb trigger upgrade will enable parallel processing of 40 Tb/s: one of the biggest data challenges in HEP.

ATLAS trigger system meets the challenges of Run 2

by Stefania Xella (University of Copenhagen), Jiri Masik (University of Manchester) for the ATLAS collaboration

The ATLAS trigger system allowed the efficient and stable collection of a rich data sample from the previous runs of the LHC.

ALICE trigger system: Present and Future

by Orlando Villalobos Baillie (University of Birmingham) for the ALICE Collaboration

Interesting physics signatures in heavy-ion collisions are either very general or very difficult to discern from the background thus posing special challenges for the ALICE trigger system. 

Trigger strategies for the LHCb experiment
