PhD forum: 2nd meeting

Second meeting in a series where PhD students of physics talk about their research. We want to create a friendly atmosphere where the youngest researchers can practice giving a talk about their work. For this reason, seniors are supposed not(!) to attend.

David Gordo's talk abstract:

We study differential cross sections for the production of three and four jets in multi-Regge kinematics, the main interest lying on azimuthal angle dependences. The theoretical setup is the jet production from a single BFKL ladder with a convolution of two/three BFKL Green functions, where two forward/backward jets are always tagged in the final state. Furthermore, we require the tagging of one/two further jets in more central regions of the detectors with a relative separation in rapidity. We found, as result, that the dependence on transverse momenta and rapidities of the central jets can be considered as a distinct signal of the onset of BFKL dynamics.

Sebastian Schwieger's talk abstract:

I will talk about aspects of bound states between 7-branes, so called T-branes. I will start by giving a very basic introduction to the relevant concepts in string theory, focussing on the arisal of gauge groups, their formulation on the world-volume theory of 7-branes and their interplay with geometry. I will then present the effect of α'-corrections on these states. Lastly, I will discuss some of the challenges in embedding such backgrounds in global compactifications.
