A bstractWe elaborate on the class of deformed T-dual (DTD) models obtained by first adding a topological term to the action of a… Expand

In this thesis we consider certain supersymmetric string theories on curved backgrounds containing the three-dimensional anti-de… Expand

We find the entire form of the amplitude of two fermion strings (with different chiralities), a massless scalar field and one… Expand

We explore the closed form of the correlation function of four spin operators (including one closed string Ramond–Ramond (RR) and… Expand

A bstractBy dealing with the evaluation of string theory correlators of $ <{V_C}{V_T}{V_{\overline{\varPsi}}}{V_{\varPsi… Expand

In this work we study the well-known contact term, which is the key element in resolving the so-called $U(1{)}_{A}$ problem in… Expand

Abstract We propose the leading couplings, in an α ′ expansion, of D-branes to Ramond–Ramond (RR) potentials in a constant NS–NS… Expand

A recent paper by Moore and Witten [1] explained that Ramond-Ramond fields in type-II superstring theory have a global meaning in… Expand

We clarify a number of issues regarding the worldsheet and spacetime descriptions of string propagation on AdS3. We construct the… Expand

Covariant actions for the bosonic fields of D = 10 IIB supergravity are constructed with the help of a single auxiliary scalar… Expand
