High Energy Theory Seminar: Normalization of Instantons in Minimal String Theory
Chitraang Murdia (University of Pennsylvania)
We match instanton contributions between minimal string theory and its dual matrix integral. The main technical insight is to use string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane. The procedure gives a finite normalization constant for the non-perturbative effects in minimal string theory. Based on arXiv:2202.03448.
