Muon Beam Tracking and Spin-Orbit Correlations for Precision g-2 Measurements
AbstractThe main goal of the Muon g – 2 Experiment (g – 2) at Fermilab
is to measure the muon anomalous magnetic moment aμ
to unprecedented precision. This new measurement will allow to test the
completeness of the Standard Model (SM) and to validate other theoretical
models beyond the SM. The close interplay of the understanding of particle
beam dynamics and the preparation of the beam properties with the experimental
measurement is tantamount to the reduction of systematic errors in the
determination of the muon anomalous magnetic moment. We describe progress in
developing detailed calculations and modeling of the muon beam delivery
system in order to obtain a better understanding of spin-orbit correlations,
nonlinearities, and more realistic aspects that contribute to the systematic
errors of the g – 2 measurement. Our simulation is meant to provide
statistical studies of error effects and quick analyses of running conditions
for when g – 2 is taking beam, among others. We are using COSY INFINITY,
a differential algebra solver developed at Michigan State University that
will also serve as an alternative to compare results obtained by other
simulation teams of the g – 2 Collaboration.
