Hope or No Hope for a String Landscape? / Sethi, Savdeep (speaker) (University of Chicago)
Whether string theory admits a multiverse of de Sitter solutions that look approximately like our universe is a hotly debated current topic. I will overview the basics of landscape constructions and explain my view on this question. [...]

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. [...]
