FONT, A e LOPEZ, J. A. Orientifolios no-supersimétricos con branas y anti-branas. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.105-108. ISSN 0035-001X.
We study type IIB orientifolds on with supersymmetry broken by compactification. We determine tadpole cancellation conditions including anti-branes and considering different actions for parity Ω. Using these conditions we then obtain the spectrum of tachyons and massless states. Various examples with N even correspond to type 0B orientifolds.
Palavras-chave : Non-supersymmetric strings; orientifolds; D-branes.
