Closed string disk amplitudes in the pure spinor formalism

Bischof, Andreas und Haack, Michael (2021): Closed string disk amplitudes in the pure spinor formalism. In: Journal of High Energy Physics, Nr. 2, 206

Abstract

We evaluate closed string disk amplitudes in the pure spinor formalism. We focus on low point functions (two- and one-point functions) but our analysis is also relevant for higher n-point functions. Amongst others we discuss issues arising due to the gauge fixing of the conformal Killing group of the disk and due to the zero mode prescription in the pure spinor formalism. As expected, in the end we find agreement with the known results from the RNS formalism.
