Konwersatorium im. Leopolda Infelda

In the first part of the talk I will summarize the present status of the Standard Theory of elementary particle interactions emphasizing the necessity of completing it in the UV (at high energies). I will argue that the Standard Model, while seemingly succesful, can at best only be an effective description of a more fundamental completion of the Standard Theory. In the second part I will try to sketch some of many theoretical proposals for a more fundamental theory that will be tested at the LHC.
