Supermoduli and PCOs at Genus Two
Charles Wang, Xi Yin
We illustrate the relation between supermoduli integration and picture changing operators (PCOs) particularly concerning the role of vertical integration, in the context of superst…
Anyon Scattering from Lightcone Hamiltonian: the Singlet Channel
Barak Gabai, Joshua Sandor, Xi Yin
We study Chern-Simons theory coupled to massive fundamental fermions in the lightcone Hamiltonian formalism. Focusing on the planar limit, we introduce a consistent regulari…
On the Equivalence between SRS and PCO Formulations of Superstring Perturbation Theory
Charles Wang, Xi Yin
We establish the equivalence between two formulations of superstring perturbation theory, one based on integration over the supermoduli space of super Riemann surfaces (SRS), the o…
D-instanton Effects in Type IIB String Theory
Nathan B. Agmon, Bruno Balthazar, Minjae Cho +2
We study D-instanton contributions to supergraviton scattering amplitudes in the ten-dimensional type IIB superstring theory beyond the leading non-perturbative order. In particula…
The S-Matrix of 2D Type 0B String Theory Part 2: D-Instanton Effects
Bruno Balthazar, Victor A. Rodriguez, Xi Yin
We study the effect of D-instantons on closed string scattering amplitudes in the two-dimensional type 0B string theory from the worldsheet perspective. We find that the contributi…
The S-Matrix of 2D Type 0B String Theory Part 1: Perturbation Theory Revisited
Bruno Balthazar, Victor A. Rodriguez, Xi Yin
We study the perturbative S-matrix of closed strings in the two-dimensional type 0B string theory from the worldsheet perspective, by directly integrating correlation functions of…
