Witten has recently proposed a string theory in twistor space whose D-instanton contributions are conjectured to compute M = 4 super-Yang-Mills scattering amplitudes. An alternative string theory in twistor space was then ...

We complete the construction of the Neveu-Schwarz sector of heterotic string field theory begun in [9] by giving a closed-form expression for the action and gauge transformations. Just as the Wess-Zumino-Witten (WZW) action ...

É apresentado um extenso estudo sobre modelos de ambitwistors. Nós construímos a ação livre da teoria de campo de cordas do ambitwistor para a corda bosônica, corda heterótica e ambos setores GSO da corda tipo II. As ações ...

The existence of an interpolating master action does not guarantee the same spectrum for the interpolated dual theories. In the specific case of a generalized self-dual (GSD) model defined as the addition of the Maxwell ...
