Siena: Editrice Compositori Bologna, n. 4, 6 p., 2000.1029-8479http://hdl.handle.net/11449/23212A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of V = 1/32g(2) which is 60% of the predicted exact minimum of V = 1/2 pi(2)g(2) from D-brane arguments.6engsuperstrings and heterotic stringsD-branesArtigoWOS:000088805700022Acesso aberto2-s2.0-6944246710
