Description
According to a proposal by Yuri Manin, we want to show that the super Mumford form is the natural measure for the perturbative computation of the string scattering amplitudes.
Starting from a formula provided by A. Voronov in 1988, we show how to get an expression for it in super-coordinates, which correctly reproduces the tree-level amplitudes for Neveau-Schwarz states, without the need to introduce ghosts and picture changing operators. We will also give some hints on how it works for Ramond states.
