We report on a two-loop supersymmetric contribution to the magnetic moment (g-2)_mu of the muon which is enhanced by two powers of tan(beta). This contribution arises from a shift in the relation between the muon mass and Yukawa coupling…
The muon anomalous magnetic moment $a_\mu$ is studied in the infinite $\tan\beta$ limit of the MSSM. Since the muon mass arises completely from loop effects, large corrections to $a_\mu$ are expected in comparison to the usual case with…
Muons are elementary particles and provide cleaner collision events that can explore higher energies compared to composite particles like protons. Muons are also far heavier than their electron cousins, meaning that they emit less…
