Research interests

Dr Archil Kobakhidze is a theoretical particle physicists working on various theoretical and phenomenological aspects of elementary particles and their fundamental interactions, gravity and cosmology.

His current research activities are focused on studies of properties of a newly discovered Higgs-like particle with the aim to uncover dynamics of the electroweak symmetry breaking and the origin of mass. He is also interested in particle physics and cosmological models that address other mysteries of nature, such as matter-antimatter asymmetry in the Universe, dark matter and dark energy.
