Soluzioni analitiche per la teoria di campo cubica di superstringa

We address the problem of ?nding solutions for generic D-brane systems in the context of cubic Open Superstring Field Theory, by appropriately using and generalizing the Erler-Maccaferri method. We ?nd subtle associativity anomalies, due to the multiple collisions of boundary condition changing operators, that were automatically avoided in the bosonic string. In the superstring case, we then ?nd a direct way of regularizing the solutions of the equations of motion, by slightly modifying the choice of the building blocks of the solution, in order to avoid such collision. The obtained solution, while regular, is nevertheless very complicated to handle. We therefore develop a new formalism, based on a star algebra automorphism, to get a new regular and more manageable solution.
