Electric-Magnetic Duality in a Class of -Compactifications of M-theory
James Halverson, Benjamin Sung, Jiahua Tian
We study electric-magnetic duality in compactifications of M-theory on twisted connected sum (TCS) manifolds via duality with F-theory. Specifically, we study the physics of…
Faking Gauge Coupling Unification in String Theory
James Halverson, Benjamin Sung
Gauge coupling unification misleads infrared observers if new gauge bosons do not simultaneously come into the spectrum. Though easy to engineer in gauge theory, the situation in s…
D Anomaly-Free Matter Spectrum in F-theory on Singular Spaces
Antonella Grassi, James Halverson, Cody Long +3
In this paper we study the 6d localized charged matter spectrum of F-theory directly on a singular elliptic Calabi-Yau 3-fold, i.e. without smoothing via resolution or deformation…
The Hodge Numbers of Divisors of Calabi-Yau Threefold Hypersurfaces
Andreas P. Braun, Cody Long, Liam McAllister +2
We prove a formula for the Hodge numbers of square-free divisors of Calabi-Yau threefold hypersurfaces in toric varieties. Euclidean branes wrapping divisors affect the vacuum stru…
On the Scarcity of Weak Coupling in the String Landscape
James Halverson, Cody Long, Benjamin Sung
We study the geometric requirements on a threefold base for the corresponding F-theory compactification to admit a weakly-coupled type IIB limit. We examine both the standard Sen l…
On Algorithmic Universality in F-theory Compactifications
James Halverson, Cody Long, Benjamin Sung
We study universality of geometric gauge sectors in the string landscape in the context of F-theory compactifications. A finite time construction algorithm is presented for $\frac4…
