Leptophilic U(1) massive vector bosons from large extra dimensions

Leptophilic U(1) massive vector bosons from large extra dimensions

We demonstrate that the discrepancy between the anomalous magnetic moment measured at BNL and Fermilab and the Standard Model prediction could be explained within the context of low-scale gravity and large extra-dimensions. The dominant contribution to (g−2)μ originates in Kaluza-Klein (KK) excitati...
