Quantum Field Theory (QFT) is the indispensable conceptual framework to describe fundamental physics. Its success is exemplified by the Standard Model (SM), a specific quantum field theory that spectacularly accounts for all observations performed so far in particle physics experiments. It is however rather clear that the SM in spite of its success cannot be the ultimate description of nature.For one thing it does not account for the dark matter that mostly constitutes galaxy halos and does not explain the origin of baryons, that make up ordinary matter. Moreover there arevarious features about its structure that cry out loud for a deeper explanation. Among these, one can mention the structure of fermion masses and mixing angles, the smallness of the QCD vacuum angle, the structure of the gauge interactions and their possible unification also including gravity, the origin of electroweak symmetry breaking. For many of those issuesit is possible, and sometimes preferable, to find an explanation from new dynamics at very short distance. In that case the new dynamics cannot be directly tested by our present experimental technology. The mystery of electroweak symmetry breaking will instead likely be solved by the direct exploration of the weak scale at the Large Hadron Collider(LHC) and at future linear colliders.In the last few decades, the open problems in particle physics have forced us to explore new territories in QFT.The great development of supersymmetry, extra-dimensions or conformal field theory are largely a result of that effort. By these studies we think we have gained valuable information about which signals to search for and how. However, in many cases we have also gained quite interesting information about QFT per se. Exact non-perturbative results in supersymmetric field theory and AdS/CFT are outstanding examples of that.In a similar way, this research proposal has a multiple orientation, towards questions of direct potential relevance to particle physics but also towards field theoretic issues, that may be more broadly relevant, in principle even to the study of condensed matter systems. Among the former class of problems, I will continue the exploration of supersymmetry and of models with a composite Higgs sector. In particular I will developed new insights to test these ideas at the LHC. I will also correlate LHC signalswith the physics of the early universe, in particular in what concerns baryogenesis.On the formal side, I plan to improve our understanding of the structure of renormalization group flows in four dimensions. In particular I will study the connection between scale and conformal invariance at the non-perturbative level. I will also pursue the construction of explicit, if only approximate, conformal field theories in four dimensions. Finally I will follow a new line of research by developing effective field theory methods to systematically describe the dynamics of fluids and solids.
