String coherent vertex operators of Neveu-Schwarz and Ramond states
Alice Aldi, Maurizio Firrotta
We present a compact expression for a coherent vertex operator in superstring theory, in the Neveu-Schwarz sector, that can be easily extended to the Ramond sector by supersymmetri…

DDF operators, open string coherent states and their scattering amplitudes
Massimo Bianchi, Maurizio Firrotta
We study interactions of string coherent states in the DDF (after Di Vecchia, Del Giudice, Fubini) formalism. For simplicity we focus on open bosonic strings. After reviewing basic…
