| contents | We find that the nonzero curvature extension of the field space for the charged leptons induces a peculiar force, leading to an elegant and simple mechanism for generating the charged lepton flavor violation (CLFV) and their anomalous magnetic moment, which has not been explored in the literature. This novel force corrects the electromagnetic vertex, leading to an effective coupling which is flavor off-diagonal at tree level. Consequently, it yields the CLFV decays with a very strongly amplified sensitivity, allowing for the CLFV probes in the small flavor-violating parameter region which is out of reach of the previous models. We point out a new type of contribution for the anomalous magnetic moment of the charged leptons, coming from the electric form factor corrected by the force emerging from the curved field space. |
