Sensitivity to new physics: ae vs. amu
Abstract
At present it is generally believed that ``new physics'' effects contribute to leptonic anomalous magnetic moment, al, via quantum loops only and they are proportional to the squared lepton mass, (ml)2. An alternative mechanism for a contribution by new physics is proposed. It occurs at the tree level and exhibits a linear rather than quadratic dependence on ml. This leads to a much larger sensitivity of ae to the new physics than was expected so far.
