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

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

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

Abstract The complete form of the amplitude of one closed string Ramond–Ramond (RR), two fermionic strings and one scalar field… 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
