Torsional Heterotic Geometries

Katrin Becker, Savdeep Sethi

We construct new examples of torsional heterotic backgrounds using duality with orientifold flux compactifications. We explain how duality provides a perturbative solution to the t…

Gravitational Wave Bursts from Cosmic Superstring Reconnections

Mark G. Jackson, Xavier Siemens

We compute the gravitational waveform produced by cosmic superstring reconnections. This is done by first constructing the superstring reconnection trajectory, which closely resemb…

Spin-Statistics Violations from Heterotic String Worldsheet Instantons

Mark G. Jackson

In this paper we consider the role that worldsheet instantons in the heterotic string could play in spin-statistics violations. Such violations are nonperturbative in the string te…

Standard Model Gauging of the WZW Term: Anomalies, Global Currents and pseudo-Chern-Simons Interactions

Jeffrey A. Harvey, Christopher T. Hill, Richard J. Hill

The standard model gauging of the Wess-Zumino-Witten term requires a modified counterterm when background fields, needed to generate the full set of currents…

Half-Twisted (0,2) Landau-Ginzburg Models

Ilarion V. Melnikov, Savdeep Sethi

We compute correlators of chiral operators in (0,2) supersymmetric Landau-Ginzburg theories. The class of theories and the correlators we study are relevant for extending and testi…

Strings ending on branes from supergravity

Oleg Lunin

We study geometries produced by brane intersections preserving eight supercharges. Typical examples of such configurations are given by fundamental strings ending on Dp branes and…
