PP-wave Green-Schwarz superstring, polygon divergent structure and conformal field theory

Mark A. Walton, Jian-Ge Zhou

In the semi-light cone gauge $g_{ab}=e^{2\varphi }{\delta }_{ab}$, ${\bar{\gamma }}^{+}\theta =0$, we evaluate the $\varphi$-dependent effective action for the pp-wave Green-Schwarz (GS) superstring in both harmonic and…
