The Cosmological Constant Problem and the Extra Dimensions of $N = 2$ $D = 5$ Supergravity

Safinaz Salem

We propose an interpretation for the cosmological constant problem based on modeling the universe as a 3-brane embedded in the bulk of 5-dimensional supergravity with hypermultiple…

The Hierarchy Problem and $N = 2$ $D = 5$ Supergravity

Safinaz Salem

We introduce a new scenario to solve the hierarchy problem based on $N = 2$ , five-dimensional supergravity compactified on Calabi-Yau threefold down from $D = 11$ s…

Low-energy theorem for $γ \to 3 π$ : surface terms against $π a_{1}$ -mixing

A. A. Osipov, M. M. Khalifa, B. Hiller

We reconsider the contribution due to $π a_{1}$ -mixing to the anomalous $γ \to π^{+} π^{0} π^{-}$ amplitude from the standpoint of the low-energy theorem $F^{π} = e f_{π}^{2} F^{3 π}$ , which relates the…
