Description

The Muon $g-2$ Experiment at Fermilab aims to measure the muon anomalous magnetic moment with the unprecedented precision of 140 parts-per-billion (ppb). In April 2021 the collaboration published the first measurement, relative to the first year of data taking. The result confirmed the previous experiment at Brookhaven National Laboratory (BNL), and increased the long-standing tension with the Standard Model prediction to 4.2 $\sigma$. By July 2022 the experiment is expected to conclude the final acquisition of positive muon data, with a total of $\sim$18 times the statistics of the BNL experiment. A collaboration-wide effort is now in place to help producing the multi-petabyte-sized data sets, a challenge typically faced by much bigger experiments. Having a quick production turnaround time is of critical importance in order to achieve the planned publication schedule. In this talk, I will describe the Muon $g-2$ production workflow, the former and current challenges, the tools involved, and the future prospects.
