Abstract:
This iteration of the journal club will take place on Zoom due to the COVID-19 pandemic. Feel free to contact Eduardo Gonzalo or Joan Quirant to be added to the mailing list and receive the Zoom invitation.
In this special SPLE guest edition, we will have Mikel A. Urkiola, who will tell us about:
ABSTRACT: In this talk I will outline the results of our recent works (arxiv:2007.10381 and 2011.13953). I will give an overview of the moduli stabilization problem in type-IIB flux compactifications in string theory, and how this issue can be treated analytically through the use of symmetries of the moduli space. Applying these methods to no-scale vacua in the Large Complex Structure (LCS) region, we will be able to obtain a closed and analytical expression for the scalar spectrum of the theory at tree-level for the complex structure and dilaton sector. Finally, we will see how these results apply for a concrete example (the octic), by a direct numerical search for vacua in that model.
The presentation will be preceded by a short discussion on recent papers.
