The mission of the Theoretical High Energy Physics group is to conduct world-class research in the areas of Quantum Field Theory, Scattering Amplitudes and Particle Physics Phenomenology, String Theory and Quantum Gravity, Non-linear Chaotic Dynamics and Complex Systems and Cosmology.

The group has a world-wide network of collaborating scientists and participates in individual and multi-partner projects funded by national and international research organizations.

The training of young researchers from the undergraduate to the postdoctoral level is a significant and systematically pursued activity of the group.

The research on Quantum Field Theory, Scattering Amplitudes and Particle Physics Phenomenology focuses in bringing theoretical predictions at the highest precision level to meet the physics analysis requirements of the collider experiments such as the LHC.

Theoretical Research for Physics Beyond the Standard Model (BSM) takes different forms ranging from attempts to extend the Gauge Principle to higher spin tensor gauge bosons with many phenomelogical signatures in the upcoming runs at the LHC and future FCC-colliders.

The effort to incorporate Gravity in the framework of the Standard Theory of EW+QCD Interactions is a standing challenge of the group researching various aspects of it ranging from the Standard Cosmological Model (Dark Matter and Dark Energy Modeling, Inflation) to Quantum Gravity approaches of Strings and Membranes as well as Quantum Black Hole Physics and its Information Paradox.

The investigation of the vacuum structure of the QCD and of the chromo-magnetic condensation. The influence of the QCD and GUT vacuum energy density on the Friedmann cosmological evolution as representing the source of the dark energy. Development of the theory of maximally chaotic dynamical systems and their application in the investigation of nonlinear dynamics of Fundamental interactions.
