The 2d CFT Distance Conjecture in CY Sigma Models
САЖЕТАК ПРЕДАВАЊА:
After introducing the CFT Distance Conjecture and its connection to the Swampland Distance Conjecture, I will discuss its realization in the context of 2d N=(2,2) Calabi-Yau sigma models. The CY degenerates at singular points in its complex-structure moduli space. Assuming a semi-stable degeneration, one can show that infinite-distance singularities always lead to a non-empty codimension-one normal-crossing intersection. By using a N=(2,2) Landau-Ginzburg model that flows to the desired sigma-model in the IR, we argue that this type of singularity leads to a continuum of states without gap in the SCFT, as required by the CFT Distance Conjecture. This argument is similar to that explaining how the worldsheet resolves a conifold singularity in string theory and recovers the continuum and the non-vanishing gap predicted by the Ooguri-Vafa 2d black hole description of the resolved conifold.
