Abstract |
The LHCb upgrade trigger represents a new paradigm in high energy physics: A fully software trigger operating at the LHC bunch crossing frequency with a triggerless readout. The existing level-0 hardware trigger in Run 2 has allowed us to test much of the upgrade strategy at 1MHz. In this talk, we will describe the performance of the Run 2 trigger in pp and special data taking configurations, and the implications for the deployment of the upgrade trigger at 30MHz.

merged with 562 Reconstruction at 30 MHz for the LHCb upgrade
In the upgrade era, the LHCb reconstruction needs to face the challenge of fulfilling the tight time constraint imposed by a fully software trigger system running at the LHC collision frequency of 30 MHz, while ensuring the high level of performances needed by the physics program. This challenge requires rethinking and optimising the logic of the algorithms, exploiting to the best the detectors properties and adopting efficient computing solutions. An overview of the current status and of the path towards further additional improvements will be presented.
