Institute for Theoretical Particle Physics (TTP)

The focus of our research at the Institute for Theoretical Particle Physics is the study of physics of elementary particles. Physics of elementary particles is successfully described by the Standard Model of Particle Physics that was proposed as the leading theory of Nature more than 40 years ago. The Standard Model is an extremely successful theory which describes a vast majority of phenomena that are observed in the Universe. Yet, theoretical shortcomings of the Standard Model suggest that this theory is incomplete and that additional, so far unknown, particles and interactions should exist. The research of the Institute contributes towards discovering the physics beyond the Standard Model through refined theoretical descriptions of Standard Model processes and through a development of specific models of New Physics.

Researches at the Institute provide theoretical support for studying Higgs boson physics at the LHC, explore the flavour structure of the Standard Model and beyond by studying properties of B and D mesons and develop new methods for performing high-precision computations in Quantum Field Theory.
