Localization of matter fields on a chameleon brane

Year: 2025

Type: article

Abstract: In this work, we address the localization problem of vector field in the chameleon braneworld and investigate the localization of various matter fields. The conditions for localizing the matter fields are determined. It is found that the zero modes of scalar, vector, and fermion fields can be successfully localized, yet the zero mode of the Kalb-Ramond field cannot be localized, which implies the recovery of standard model fields on the brane. Furthermore, the characteristics of quasi-localized modes of the q -form fields are analyzed, and the parameter constraints of the model are estimated.
