On Towers and Scalars / Ibanez , Luis (speaker) (Universidad Autonoma de Madrid (ES))
We study three topics concerning the role of scalars and the distance conjecture in the Swampland program. First we discuss a Scalar Weak Gravity Conjecture (SSWGC). [...]

Deep Reinforcement Learning and the Type IIA Landscape / Nelson, Brent (speaker) (Northeastern University)
An artificial intelligence agent known as an asynchronous advantage actor-critic is utilized to explore type IIA compactifications with intersecting D6-branes. By reinforcement learning, the agent's performance in satisfying string consistency conditions, and finding Standard Model like configurations, is significantly improved. [...]

Complexity and Random Matrix Approximations / Halverson, James (speaker)
Efforts to better understand the landscape and swampland can be stifled by computational complexity. I will discuss ways in which complexity could be overcome by learning random matrix approximations to string data, including both opportunities and caveats. [...]

The Flatness of Axionic Potentials and a 10d Approach to KKLT / Hebecker, Arthur (speaker) (Heidelberg University)
After a brief summary of some recent work on flat axionic potentials in the regime of subplanckian decay constants, I will turn to the controversial topic of a 10d description of the KKLT scenario. In particular, I will outline a proposal for completing the coupling of D7-brane gauginos to bulk fields. [...]

Generic matter and global gauge group structure in 6D and 4D supergravity and F-theory models / Taylor, Washington (speaker)
6D supergravity and F-theory geometry provide compatible frameworks for a well-defined notion of genericity for matter representations. Generic matter types depend on global gauge group structure, giving insight in particular into the distinction between theories with gauge group SU(3) x SU(2) x U(1) and those with SU(3) x SU(2) x U(1)/Z_6..

On de Sitter realisations in gravity and string theory / Kiritsis, Elias (speaker) (APC et UoC)
We explore non-standard realizations of de Sitter solutions in string theory and associated theories of gravity based on ideas of the AdS/CFT correspondence..

Classification of Left-Right Symmetric Heterotic String vacua / Percival, Benjamin (speaker) (liverpool)
I will briefly describe the classification approach within the free fermionic formalism, then discuss techniques beyond the random generation classification. In particular, explorations of 'fertile regions' within left-right symmetric models that are pre-selected at the SO(10) level for phenomenological favourability. [...]

Geometrical destabilisation of light fields in String Inflation / Guidetti, Veronica (speaker) (University of Bologna)
A typical feature of 4D string models is the presence, at tree-level, of a plethora of massless fields called moduli. Some of them are axion-like fields which become massive only via tiny non-perturbative effects which tend to make them naturally very light. [...]

Discrete Flavor Symmetries from Orbifold GUTs / Muetter, Andreas (speaker) (Technical University of Munich)
In this talk, we show that in orbifold GUT models discrete symmetries can be understood as remnants of gauge symmetries that are broken by orbifold boundary conditions. We present a systematic way to determine the discrete symmetries that survive the orbifolding. [...]
