Gauge Theory Dynamics and Kahler Potential for Calabi-Yau Complex Moduli
arXiv:1309.2305 · doi:10.1007/JHEP12(2013)099
Abstract
We compute the exact two-sphere partition function and matrix of two-point functions of operators in the chiral ring with their complex conjugates in two-dimensional supersymmetric gauge theories. For gauge theories that flow in the infrared to a Calabi-Yau nonlinear sigma model, these renormalization group invariant observables determine the exact Kahler potential and associated Zamolodchikov metric in the complex structure moduli space of the Calabi-Yau manifold.
