Comments on Unstable Branes

Ken Intriligator, Matt Kleban, Jason Kumar

We argue that type II string theories contain unstable NS4 branes, which descend from a conjectured unstable M4 brane of M-theory. Assuming that an M2 brane can arise in M5 brane/a…

Examples of stationary BPS solutions in N=2 supergravity theories with R^2-interactions

G. L. Cardoso, B. de Wit, J. Käppeli +1

We discuss explicit examples of BPS solutions in four-dimensional N=2 supergravity with R^2-interactions. We demonstrate how to construct solutions by iteration. Generically, the p…

Bosonic M Theory

Gary T. Horowitz, Leonard Susskind

We conjecture that there exists a strong coupling limit of bosonic string theory which is related to the 26 dimensional theory in the same way that 11 dimensional M theory is relat…

Gauge Invariant Correlators in Non-Commutative Gauge Theory

Moshe Rozali, Mark Van Raamsdonk

Using perturbation theory, we explore the universal high momentum behavior of correlation functions of gauge invariant operators in planar noncommutative gauge theories. We find th…

Low-energy propagation modes on string network

Naoki Sasakura

We study low-energy propagation modes on string network lattice. Specifically, we consider an infinite two-dimensional regular hexagonal string network and analyze the low frequenc…

Closed strings from nothing

Matthew Kleban, Albion Lawrence, Stephen Shenker

We study the physics of open strings in bosonic and type II string theories in the presence of unstable D-branes. When the potential energy of the open string tachyon is at its min…
