Can compactifications solve the cosmological constant problem? by Masoumi, Ali, Hertzberg, Mark Peter

“…Recently, there have been claims in the literature that the cosmological constant problem can be dynamically solved by specific compactifications of gravity from higher-dimensional toy models. …”
