High Energy Physics

High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

9th CEEC competition: Expressions of Interest to Join Gr@v

The Gr@v research group invites expressions of interest from researchers wishing to apply to the forthcoming 9th edition of the Individual Call to Scientific Employment Stimulus (CEEC Individual), funded by the Portuguese Foundation for Science and Technology (FCT).

The CEEC Individual programme offers competitive funding for three-year research contracts, providing an opportunity for talented researchers to develop their scientific careers in Portugal.

New CIDMA scientific coordinator

Carlos Herdeiro, Gr@v member and founder, took office on 1 October as the new Scientific Coordinator of CIDMA, beginning a four-year term. The new coordination team also includes Natália da Costa Martins, Maria Elisa Carrancho Fernandes, and Nelson Filipe Loureiro Vieira. UA News coverage here. We wish the team every success in this new chapter.
