The Institute for Theoretical Physics offers the following seminars:
Rosetta has been at comet Churyumov-Gerasimenko almost 1.5 years by now and the ten instruments on board the European Space mission Rosetta are very busy studying the comet nucleus and its coma. The two Swiss ROSINA mass spectrometers and the pressure sensors are exploring the volatile material in the coma over a wide range of heliocentric distances. In the talk I will present some of the highlights from ROSINA and other instruments on board and discuss their first implications and conclusions on the origin of our solar system material.

Evidence for dark matter is overwhelming. From experimental data we can infer that dark matter constitutes most of the matter in the Universe and that it interacts very weakly, and at least gravitationally, with ordinary matter. However we do not know what it is. Several theoretical models have been proposed that predict the existence of Weakly Interacting Massive Particles (WIMPs) that are excellent dark matter candidates. The existence of WIMPs can be tested indirectly, primarily through their annihilation or decay into photons. In this talk I’ll present the latest results on these searches.

It is widely accepted that N=4 Super-Yang-Mills theory is integrable in the planar limit. In this talk, I will review the developments in computing three-point functions using the powerful tools of integrable systems in the past five years. I will explain the basic ideas and then discuss several interesting cases and their relations to other domains of mathematical physics.

We present the calculatation of the fully differential next-to-next-to-leading-order (NNLO) corrections to vector-boson fusion (VBF) Higgs production at the LHC, in the limit in which there is no cross-talk between the hadronic systems associated with the two protons. We explain the new "projection-to-Born" method that we used to combine an inclusive NNLO calculation in the structure-function approach and a suitably factorised next-to-leading-order (NLO) VBF Higgs plus 3-jet calculation. An earlier calculation of the fully inclusive cross section had found very small NNLO corrections, at the 1% level. In contrast, we find that the cross section after typical VBF cuts receives NNLO contributions of about 5-6%, and that standard differential distributions show corrections of up to 10-12%. These corrections are often outside the NLO scale-uncertainty band.
