Description

Abstract: The muon’s anomalous magnetic moment, aμ, provides a unique way for probing physics beyond the standard model experimentally as it gathers contributions from all the known and unknown forces and particles that couple to magnetic moments. The theoretical prediction of aμ has been in greater than 3 σ tension with the experimental measurement since the results of the Muon g-2 Experiment at the Brookhaven National Laboratory (E-821) were published in the early 2000s with a precision of 540 ppb, hinting towards a possibility of existence of physics beyond the standard model. To settle this tension, the new Fermilab Muon g - 2 Experiment (E-989) is currently taking data with the aim of experimentally determining aμ with a final precision of 140 ppb. In this talk I will describe the experimental principle and give an overview of the Run-1 results published in April last year along with the current status of the experiment.
