Small dark energy and stable vacuum from Dilaton–Gauss–Bonnet coupling in TMT
Abstract In two measures theories (TMT), in addition to the Riemannian measure of integration, being the square root of the determinant of the metric, we introduce a metric-independent density $$\Phi $$ Φ in four dimensions defined in terms of scalars $$\varphi _a$$ φ a by $$\Phi =\varepsilon ^{\mu...
