Conformal defects as solution-generating symmetries for D-branes
Costas Bachas
(ENS Paris)
Abstract:
Using the example of WZW D-branes, I will explain how loop operators, corresponding to bulk conformal defects, generate new consistent D-branes from old ones. I will comment on possible extensions to more general geometries.

D-branes on threefolds and quiver sheaves
Balazs Szendroi
(Utrecht and Oxford)
Gauge Theory Amplitudes, MHV rules and Twistor Space
Valentin Khoze
(Durham)
Abstract:
I will give an introduction to the novel method of calculating scattering amplitudes in gauge theory with twistor-space string theory inspired rules. I will show how the method works in simple cases and discuss recent new results for the amplitudes obtained at tree and loop level. I'll discuss some known puzzles, the ways to resolve them, open questions and future directions, including issues in string theory, quantum field theory and phenomenology.
