Bound-states of D-branes in L-R asymmetric superstring vacua

نویسنده

چکیده

We discuss bound-states of D-branes in truly L-R asymmetric and thus non-geometric Type II vacuum configurations with extended supersymmetry. We argue for their stability as a result of residual supersymmetry and coupling to R-R potentials surviving in the massless spectrum. We then identify the open string excitations of these L-R asymmetric BPS D-branes. Finally, we briefly comment on possible applications and extensions.

From Twists and Shifts to L-R asymmetric D-branes

In the first part of the talk, we discuss non-geometric twists and shifts and briefly review asymmetric orbifolds and free fermion constructions. These allow us to build Type IIB models with N = 1L + 1R and N = 1L + 0R models having few or no moduli. We then consider unoriented projections of the former and (‘exotic’) D-branes in the latter. In the second part, devoted to L-R asymmetric D-brane...

A Note on Toroidal Compactifications of the Type I Superstring and Other Superstring Vacuum Configurations with 16 Supercharges

We show that various disconnected components of the moduli space of superstring vacua with 16 supercharges admit a rationale in terms of BPS un-orientifolds, i.e. type I toroidal compactifications with constant non-vanishing but quantized vacuum expectation values of the NS×NS antisymmetric tensor. These include various heterotic vacua with reduced rank, known as CHL strings, and their dual typ...

Type I Superstrings without D-branes

Notwithstanding the central role of D-branes in many recently proposed string dualities, several interesting type I vacua have been found without resorting directly to D-brane technology. In this talk, we analyze a three-generation SO(8) × U(12) chiral type I model with N = 1 supersymmetry in D = 4. It descends from the type IIB compactification on the Z orbifold and requires only Neumann bound...

Lectures on Superstring and M Theory Dualities 1

These lectures begin by reviewing the evidence for S duality of the toroidally compactiied heterotic string in 4d that was obtained in the period 1992{94. Next they review recently discovered dualities that relate all ve of the 10d superstring theories and a quantum extension of 11d supergravity called M theory. The study of p-branes of various dimensions (some of which are D-branes) plays a ce...

Constructing D-branes from K-theory

A detailed review of recent developments in the topological classification of D-branes in superstring theory is presented. Beginning with a thorough, self-contained introduction to the techniques and applications of topological K-theory, the relationships between the classic constructions of K-theory and the recent realizations of D-branes as tachyonic solitons, coming from bound states of high...
