Toward the Gravity Dual of Heterotic Small Instantons
Fang Chen, Keshav Dasgupta, Paul Franche +1
The question of what happens when the heterotic SO(32) instanton becomes small was answered sometime back by Witten. The heterotic theory develops an enhanced Sp(2k) gauge symmetry…
Metastable dark matter mechanisms for INTEGRAL 511 keV rays and DAMA/CoGeNT events
James M. Cline, Andrew R. Frey, Fang Chen
We explore dark matter mechanisms that can simultaneously explain the galactic 511 keV gamma rays observed by INTEGRAL/SPI, the DAMA/LIBRA annual modulation, and the excess of low-…
Supersymmetric Configurations, Geometric Transitions and New Non-Kahler Manifolds
Fang Chen, Keshav Dasgupta, Paul Franche +2
We give a detailed derivation of a supersymmetric configuration of wrapped D5-branes on a two-cycle of a warped resolved conifold. Our analysis reveals that the resolved conifold s…
