Diffeomorphism in Closed String Field Theory
Ben Mazel, Charles Wang, Xi Yin
We explain how the spacetime diffeomorphism in the classical bosonic closed string field theory (SFT) is represented as gauge transformations in weakly curved background…

Conformal Perturbation Theory and Tachyon-Dilaton Eschatology via String Fields
Ben Mazel, Joshua Sandor, Charles Wang +1
We analyze deformations of two-dimensional conformal field theory (CFT) from the perspective of classical bosonic closed string field theory (SFT). The latter can be viewed as a ve…
