Brane-like states are defined by physical vertex operators in NSR superstring theory, existing at nonzero pictures only. These states exist both in open and closed string theories, in the NS and NS-NS sectors respectively. In this paper we present a detailed analysis of their BRST properties, giving a proof that these vertex operators are physical, i.e. BRST invariant and BRST non-trivial.

Discrete physical states and correction terms in the Supersymmetric c=1 Model of String Theory.

In this work, we explore the example of supersymmetric c=1 model which is one of the simplest models of superstrings, with an elegant and transparent spectrum of physical states. We show how the

Classical gauge instantons from open strings

We study the D3/D(-1) brane system and show how to compute instanton corrections to correlation functions of gauge theories in four dimensions using open string techniques. In particular we show that

D-brane dynamics in constant Ramond-Ramond potentials, S duality and noncommutative geometry

We study the physics of D-branes in the presence of constant Ramond-Ramond potentials. In the string field theory context, we first develop a general formalism to analyze open strings in gauge
