Similarity of the gravitational contributions to anomalous magnetic moment
Konosuke Sawa
Abstract
A precise measurement of a muon (g-2) experiment recently reported a deviation from the Standard Model. This implies the need to an extension of the model and suggests underlying mechanisms. We hypothesize that the influence of higher dimensional gravity causes this (g-2) deviation. This effect would appear as Kaluza-Klein modes and Nambu-Goldstone modes on a 3-brane. These classical effects produce new contributions to the magnetic moment. In this paper, we perform a consistency check by comparing the results derived from the Born and Schrödinger approximations. This comparison reveals a similarity between KK-dilaton modes and the brane stretching effect.
