Study of potential lifetime bias in the LHCb reconstruction software for Run 3 — •Paula Herrero Gascón and Peilian Li — University of Heidelberg, Physikalisches Institut Heidelberg, Germany
The upgraded LHCb experiment will restart data taking in spring 2022 at an instantaneous luminosity of up to 2 × 1033 cm−2 s−1. To effectively select the interesting b and charm hadron events at these high rates a full software trigger system is required. The entire reconstruction framework and its algorithms have been reimplemented and optimized. To be well-prepared for the coming data taken, it is essential to validate the physics performance for this completely new system. The precise reconstruction of the decay-time of b hadrons is vital for many time-dependent physics measurements at LHCb. This talk will focus on a performance study of the decay-time reconstruction for Run 3 and investigate potential reconstruction-induced biases.
