Abstract

Reconstructing the vertices of primary interactions at the LHCb experiment is an essential part of its online data acquisition sequence. The quest for ever higher rates and luminosities gives raise to new challenges for such algorithms. The LHCb Upgrade detector will start taking data in 2021 at an instantaneous luminosity of L = 2 × 10³³ cm^-2 s^-1. A RAMP challenge on fast primary vertex reconstruction using simulated data under such conditions was performed at the RAPID2018 workshop held in November 2018 in Dortmund with the aim of exploring new techniques and ideas to solve this problem.
