Localization of Bulk Form Fields on Dilatonic Domain Walls

TL;DR

This paper investigates how bulk form fields of various ranks can be localized on dilatonic domain walls, revealing that localization depends on the dilaton coupling parameter and can include forms of the same or lower rank.

Contribution

It demonstrates that bulk form potentials of any rank can be localized on dilatonic domain walls, with localization properties influenced by the dilaton coupling parameter, including cases of multiple ranks.

Findings

Bulk form potentials of any rank can be localized as same or lower rank forms.

Large dilaton coupling allows localization as both same and lower rank forms.

Localization depends on the dilaton coupling parameter value.

Abstract

We study the localization properties of bulk form potentials on dilatonic domain walls. We find that bulk form potentials of any ranks can be localized as form potentials of the same ranks or one lower ranks, for any values of the dilaton coupling parameter. For large enough values of the dilaton coupling parameter, bulk form potentials of any ranks can be localized as form potentials of both the same ranks and one lower ranks.
