Arbitrary p-form Galileons
We show that scalar, 0-form, Galileon actions—models whose field equations contain only second derivatives—can be generalized to arbitrary even p-forms. More generally, they need not even depend on a single form, but may involve mixed p combinations, including equal pmultiplets, where odd p fields are also permitted: We construct, for given dimension D, general actions depending on scalars, vec...
متن کاملVariations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملMultifield Galileons and Higher Codimension Branes
In the decoupling limit, the Dvali-Gabadadze-Porrati model reduces to the theory of a scalar field π, with interactions including a specific cubic self-interaction—the Galileon term. This term, and its quartic and quintic generalizations, can be thought of as arising from a probe 3-brane in a five-dimensional bulk with Lovelock terms on the brane and in the bulk.We study multifield generalizati...
متن کاملruby of the sky
in a profoundly impressive verse in shahnameh, sky is likened to red ruby. the present paper is attempted to probe into the background of the conventional belief regarding the relationship between sky and stone, for the semantic structure of the verse is composed in such a way that it is not possible to consider this relationship as being a conceptualistic viewpoint so that one may establish so...
