A 40 MHz Trigger-free Readout Architecture for the LHCb Experiment / Alessio, F (CERN) ; Jacobsson, R (CERN) ; Guzik, Z (Lodz, IPJ)
The LHCb experiment is considering an upgrade towards a trigger-free 40 MHz complete event readout in which the event selection will only be performed on a processing farm by a high-level software trigger with access to all detector information. This would allow operating LHCb at ten times the current design luminosity and improving the trigger efficiencies in order to collect more than ten times the statistics foreseen in the first phase. [...]
