Vertex Operators in Superstring Theory from Integral Forms and Descent Equations
Isao Kishimoto, Shigenori Seki, Haruka Shimogaki +1
We develop a geometric formulation of vertex operators in superstring theory based on integral forms on super Riemann surfaces. Starting from the integrated NS-NS vertex operator,…

Closed string vertex operators with various ghost number
Isao Kishimoto, Mako Kouga, Shigenori Seki +1
We construct closed string vertex operators with various ghost numbers in addition to the conventional ones, using the Faddeev-Popov procedure for the gauge fixing of the conformal…

Two-point closed string amplitudes in the BRST formalism
Isao Kishimoto, Shigenori Seki, Tomohiko Takahashi
Two-point tree-level amplitudes in bosonic closed string theory are described by a correlation function within the BRST formalism, which respects manifest Lorentz and conformal inv…
