In this paper, a covariant version of multi-localizing q-form fields is proposed, showing that all q-form fields have an ultralight mode with the same mass as the gravitational one. This suggests that there is an universal mass scale for the ultralight modes of the bosonic fields.
In this paper we find an universal mass scale for all q-forms in multi-brane worlds model. It is known that this model provides an ultralight mode for the fields. However, to get this, the Lagrangians considered in the literature are not covariant. In order to solve this, we propose a covariant version to multi-localize q-form fields. As a consequence of the covariance, we show that all the q-form fields have an ultralight mode with the same mass as the gravitational one. That way we show that there is an universal mass scale for the ultralight modes of the bosonic fields. This suggests that a new physics must emerge, for all these fields, at the same scale.
