A Lapse in the Cosmological Constant Problem with Bulk Dynamics
Justin Khoury, Benjamin Muntz, Antonio Padilla
We have previously proposed a new approach to the cosmological constant problem based on anisotropic scaling in a compact extra dimension. In the ultra-local limit, the inter…

Small Vacuum Energy and Tunneling in a Modified Bousso-Polchinski Model
James Halverson, Justin Khoury, Cody Long
We propose a simplified model for the cosmological constant in string theory flux vacua motivated by type IIB and F-theory compactifications. Relative to the Bousso-Polchinski mode…

A Lapse in the Cosmological Constant Problem
Justin Khoury, Benjamin Muntz, Antonio Padilla
We present a new mechanism for addressing the cosmological constant problem based on global constraints arising from a lapse function in a higher-dimensional gravitational theory.…
