Fine-tuning with brane-localized flux in 6D supergravity
Fine-tuning with brane-localized flux in 6D supergravity
There are claims in the literature that the cosmological constant problem could be solved in a braneworld model with two large (micron-sized) supersymmetric extra dimensions. The mechanism relies on two basic ingredients: first, the cosmological constant only curves the compact bulk geometry into a rugby shape while the 4D curvature …
