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.

For our latest developments/activities in this area, please see the listing below.

Latest High Energy Physics News & Events

Black Holes Go South

In the last week of January 2026, a research school on black holes and related topics took place in the beautiful setting of Licán Ray, Chile, nestled in a stunning volcanic lake region. C. Herdeiro was among the invited lecturers, with sessions held - quite fittingly - on whiteboards set up in the garden. The combination of great science and a relaxed, inspiring atmosphere made for a truly memorable event. Many thanks to Adolfo Cisterna and his team for making it all possible.

Tracing Curvature: Where Art Meets Science

On January 20th, 2026, the art–science exhibition was officially (re)opened at Fábrica - Centro Ciência Viva de Aveiro. The event was hosted by Fábrica’s director, Pedro Pombo, and brought together the head of the Department of Mathematics, Alexandre Almeida, and the director of CIDMA, Delfim Torres, along with several colleagues. This initiative is another step in sharing the beauty of science with a broader audience, strengthening the connection between scientific research and society.

Haroldo Lima Junior in Aveiro

Our friend and collaborator Haroldo Junior visited Aveiro for a few weeks in February 2026. A former PhD student in Belém/Aveiro and now a faculty member at Universidade Federal do Maranhão in São Luís, it was a pleasure to have him back. In the photo, Haroldo is joined by our very esteemed secretary, Cristina.
