Journal ArticleDOI
Machine learning in the string landscape
TL;DR: In this paper, a decision tree accurately predicts the number of weak Fano toric threefolds arising from reflexive polytopes, each of which determines a smooth F-theory compactification, and linear regression generates a previously proven conjecture for the gauge group rank.
Journal ArticleDOI
Global F-theory models: instantons and gauge dynamics
Mirjam Cvetič,Mirjam Cvetič,Iñaki García-Etxebarria,Iñaki García-Etxebarria,James Halverson,James Halverson +5 more
TL;DR: In this paper, a compact F-theory GUT model is presented, in which D-brane instantons generate the top Yukawa coupling non-perturbatively.
Journal ArticleDOI
Realistic Yukawa structures from orientifold compactifications
TL;DR: In this paper, the conditions under which D-brane instantons will induce these missing couplings without generating other phenomenological drawbacks, such as R-parity violating couplings or a?-term which is too large.
Journal ArticleDOI
Branes with Brains: Exploring String Vacua with Deep Reinforcement Learning
TL;DR: An artificial intelligence agent known as an asynchronous advantage actor-critic is utilized to explore type IIA compactifications with intersecting D6-branes to solve various string theory consistency conditions simultaneously, phrased in terms of non-linear, coupled Diophantine equations.
Journal ArticleDOI
Algorithmic universality in F-theory compactifications
TL;DR: In this paper, the universality of geometric gauge sectors in the string landscape in the context of F-theory compactifications was studied and a finite time construction algorithm was presented for geometric gauge groups.
