Scalar field

A scalar field is a Function (mathematics) function, defined in a spatial region, that assigns for some variable in theoretical physics (or pure mathematics) a single number (in the Real number real field or the Complex number complex field) for every point in the spatial region. The scalar numbers may represent a dimensionless quantify or a physical quantity expressed in physical units. Quotes The last few decades have provided abundant evidence for physics beyond the two standard models of particle physics and Lambda-CDM model cosmology. As is now known, the by far largest part of our universe's matter/energy content lies in the `dark' and consists of dark energy and dark matter. Despite intensive efforts on the experimental as well as the theoretical side, the origins of both are still completely unknown. Screened scalar fields have been hypothesized as potential candidates for dark energy or dark matter. Among these, some of the most prominent models are the Chameleon particle chameleon, symmetron, and environment-dependent dilaton.

Are there any new elementary scalars not yet discovered with masses below the mass of the Standard Model SM-like Higgs boson? For example, do axion-like particles exist? ...8. If additional scalars are discovered, how will these discoveries impact the question of the stability of the electroweak vacuum?9.
