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…
The Desert and the Swampland
Cody Long, Miguel Montero, Cumrun Vafa +1
The most natural expectation away from asymptotic limits in moduli space of supergravity theories is the desert scenario, where there are few states between massless fields and the…
PQ Axiverse
Mehmet Demirtas, Naomi Gendler, Cody Long +2
We show that the strong CP problem is solved in a large class of compactifications of string theory. The Peccei-Quinn mechanism solves the strong CP problem if the CP-breaking effe…
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…
Non-Holomorphic Cycles and Non-BPS Black Branes
Cody Long, Artan Sheshmani, Cumrun Vafa +1
We study extremal non-BPS black holes and strings arising in M-theory compactifications on Calabi-Yau threefolds, obtained by wrapping M2 branes on non-holomorphic 2-cycles and M5…
Superradiance in String Theory
Viraf M. Mehta, Mehmet Demirtas, Cody Long +3
We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance exclud…
