description During the first long shutdown of the LHC (2013-2014), the LHCb detector remained essentially unchanged, while the trigger system has been completely revised. Upgrades to the LHCb computing infrastructure have allowed for high quality decay information to be calculated by the software trigger, making separate offline event reconstruction unnecessary. The storage space of the triggered candidate is an order of magnitude smaller than the entire raw event that would otherwise need to be persisted. An application has been designed to process the information calculated by the trigger, with the resulting output used to directly perform physics measurements. Reaching the ultimate precision of the LHCb experiment in real time as the data arrive has the power to transform the experimental approach to processing large quantities of data.
