Titre Recent developments in superstring field theory 2/3
Résumé I will review some recent developments of type II and heterotic superstring field theory. The approach I will follow is due to Ashoke Sen and based on the construction of the open-closed bosonic string field theory by Zwiebach. Particular attention will be devoted to the three main challenges faced by superstring field theory: inclusion of the Ramond sector, removal of spurious singularities due to the superconformal ghosts and definition of a prescription for the off-shell amplitudes. The plan is the following: 1) motivations, divergences in (super)string theory and off-shell amplitudes; 2) superstring field theory: gauge fixed and quantum action, construction of the Ramond sector 3) momentum representation of amplitudes, applications: unitarity, soft theorems
