High energy physics is a very dynamic area of research at the moment. The forthcoming results from the Large Hadron Collider (LHC) at CERN will probe our picture of the fundamental physics governing particle interactions and hopefully uncover physics beyond the Standard Model (SM). The SM of particles physics describes three fundamental interactions acting between the constituents of matter, the quarks and leptons. The matter particles, distinguished by their ``flavour" quantum number are grouped into three different generations. Flavour physics studies the transitions between these three generations. In the SM the only source of flavour violation is the Cabibbo-Kobayashi-Maskawa (CKM) matrix. In the current LHC era after the discovery of the SM Higgs the focus of particle physics is on the discovery of new laws of physics beyond the SM. Flavour physics is an excellent tool to probe this new physics (NP). Flavour changing processes, especially flavour changing neutral current (FCNC) processes, are very sensitive to NP because they are highly suppressed (both by small CKM elements and loop-factors) in the SM. Several decays play a prominent role in the study of NP effects in flavour physics: On one hand the data for the processes b->s(d)gamma, Bs->mu mu Kaon mixing, D mixing, mu-> e gamma and mu->eee agree very well with the SM expectation and they put stringent bounds on the flavour structure of physics beyond the SM. On the other hand, there are possible hints towards new physics in B-> (D^*)tau nu and in the anomalous magnetic moment of the muon. Furthermore, the established presence of Dark Matter at astrophysical scales even requires physics beyond the SM. In a specific model of NP, the processes mentioned above are correlated and one cannot only constrain the flavour structure of the model but also study the correlations between the different observables. Furthermore, also in a model independent effective field theory approach in which the SM is supplemented with higher dimensional operators, gauge invariance still enforces correlations among different observables. It is very interesting to investigate if it is possible to explain the deviations from the SM while still being in agreement with all other measurement because this can shed light on the viability of the model under investigation. In such an analysis also the direct constraints from the LHC, electroweak precision observables, Higgs physics and the dark matter (DM) relic abundance in the universe play an important role and should be taken into account. Thus combining flavour physics with collider physics and cosmology is a key strategy in order to discover NP and to map out the theory superseding the SM.The main focus of this proposal is on multi-loop calculation for flavour observables in the Minimal Supersymmetric Standard Model (MSSM) (and possible non-minimal extensions of the Higgs sector) and on calculation in the SM extended with dimension-6 operators which are invariant under the SM gauge group. This proposal is divided into six subprojects:a) 2-loop electroweak corrections to quark-quark-Higgs couplings in the MSSM.b) B-> mu mu at NLO in QCD in the MSSM.c) b-> s gamma at NLO in QCD in the MSSM.d) Flavour-violating Higgs decays in the MSSM and 2HMDs.e) LFV observables in the SM extended with dimension 6 operators.f) Radiative neutrino masses in the R-parity conserving MSSM.
